I should check out this film, I've heard a bit about it, but never did see it. I assume the score is fantastic, if it was mentioned here.
I do hope you find that track. Though, I've run into this often with studio soundtracks. The execs leave off certain tracks because they weren't very long, or didn't include main themes or weren't during a particularly interesting part of the film. I find that very frustrating, but we often have to live with it. I, being a perfectionist, end up recording the scene with the score piece included right onto my computer. Then, I transfer it to my MP3 player. It's not always the best quality, but I do end up "having" the track. You might try that.
