It is never intended to actually break a tie between two versions; if you do wind up using it to sort then you are in trouble (two people published a development version that happened to be n commits above the last tag...). The last component only tells you that 1.8.1.301.x and 1.8.1.301.y are not the same version, not that one should be greater or less than the other. I am OK with the PEP 386 restrictions. You can convert git's hex id to decimal ;-)
