More game return policy talk! (sorta)

This is rather ironic, but yesterday I bought Call of Duty 4, Orange Box, and Rainbow 6 Vegas for 360, all new. I have been playing COD4 for probably 8 of the last 24 hours total and beaten the game, so I wanted to try the multiplayer. For some reason my xbox live wasn't connecting so I picked up the 360 for a second to reattach the wireless adapter and all of a sudden the 360 starts making this really horrible noise, and I shut the console off ASAP and took out the COD4 disc and examined it to find a perfect circular scratch on it, very noticeable with the naked eye.

Anyways, Gamestop's return policy is a little confusing when it comes to these situations. Am I able to get a refund here? All I want is another copy of COD4, not a different game or a cash refund.
