Actually, for most games, the Xbox 360 and GFWL versions get their own 1,000 gamerscore. The only game I can think of that this isn't true is Shadowrun. MS claims the reason for that with Shadowrun is the 2 versions can play against each other.
I have both versions on my games played list for the following games that I can think of.
Gears of War
Batman: Arkham Asylum
Kane & Lynch
