Okay, so I took the disc to my local Hastings and they repaired the disc for two bucks. I just tried playing it, and it made it past the scene that it usually froze on. It had a little bit of a freezing issue, but after a gentile tap on my PS3, it played fine. Hooray!!!! The clerk at Hastings was even like "oooo, I hope this works. This game is rare."
