Plot hole: Check out the final routine at the end of the movie for the Clovers. Watching carefully, approximately 20 seconds into the routine you will see two girls on the left hand side running face to face into each other. If this had been a proper competition they would have lost because it was a major error in the routine.
Plot hole: In the final cheerleading sequence for the Toros, it is obvious that the middle stunt falls. Instead of reshooting, they kept the mistake in. The team wouldn't have been "up there" with the Clovers if it were an actual competition.
