I don't know that there is anything resembling a "standard" warranty for this type work - most plumbers warranty their work for a month, some for 3, rarely for 6 months to a year - so in your case I don't think there is a "right" warranty period among those two bids.

For this type of work, the warranty probably is a lot less meaningful than for many other types of job - this sort of repair, if it fails, will likely do so either basically right away (within days, due to sloppy workmanship or such) or else many years down the road as the connections go bad, so I can't see paying $500 more for another 9 months warranty. I would put more emphasis on a quality contractor with good reviews. Also, if you tell the low bidder you have another bid you are considering that has offerred a year warranty, he might well volunteer to meet that for less than $500 additional $, knowing the risk of it leaking is VERY minimal. I would be slightly more interested in a warranty i the whole line is being replaced than if it is just a spot repair - but if the line is properly embedded in bedding sand for about 3-4 inches all around the line to prevent punctures from rocks in the native backfill (more like 3-6 inches of pea gravel around 3 inches of sand if soil is very rocky or bouldery and the larger rocks are not scraped out before backfilling the first foot or so of the ditch) the risk of the line going bad during a warranty period beyond a month or so is very low too.

The thing that would worry me is the total bid amount - I would be looking for another bid or three, because gas service lines are almost always quite shallow (a foot or two) so digging is not a major expense, and do not have to follow a straight line, so commonly even for a total line replacement (unless in hard bedrock) they would just dig a new trench a few feet off the current alignment (or right along it maybe if the existing line is already totally out of service right now and is plastic) and install a new line. Commonly more like $500-1000 with normal burial depth, taking typically about 2-3 hours for typical 25-50 foot run (assuming no nasty accessibility issues and not digging up street). Might be another couple hundred range for the utility to do the connection in the trench which the contractor opens up. If under drive or through gardens/lawns which you will be paying to have repaired afterwards, then of course total project cost goes up a few hundred $ or more depending on what you are going through.

If looking at a spot leak, not an entire line replacement, typically about $250-500 range (unless under big tree or drive or such) unless the ground needs thawing first, then about $100-200 additional for that.

So - although this presumably is an "emergency" so you may be paying premium price, you would have to decide whether to pay the $2500-3000 or go for other bids. If you are out of gas service and it is cold out, that might limit your choices - though many gas companies will provide an above-ground flexible tubing bypass for the short term until the replacement can be done.

I also wonder if you have contacted your gas company (assuming this is your gas supply line, not a line to a pool or barbecue or such) - normally the line to the meter is THEIR responsibility and you would pay only for remediation of anything they have to dig through to get the line fixed/replaced, as applicable. So you might get this done for free or nearly so, assuming the leak is not due to damage you or construction at your place caused.
