Where is it registered? If it's registered at GoDaddy, you should visit their GoDaddy Auctions, because (I forget the exact dates) they will offer your domain for auction from about day 27 after expiry for about 10 days. Needless to say you should bid only just before the last three minutes of the auction.
I wouldn't really bother with a GoDaddy Backorder. They are not very good at capturing domains unless they drop and aren't immediately picked up by a drop-catcher.
Since it is still recently expired, you would be better off buying the domain in a Pre-Release Auction. But we need to know where it is registered. If at GoDaddy, then what I described above would be GoDaddy's version of a Pre-Release auction.
