What do trophies from competition have to do with being a mcdojo?
If anything, I'd say that winning a lot of trophies at regional and national tournaments (not "in-house tournaments") is a sign the school is less likely to be a Mcdojo. It shows that the school produces students who are fairly skilled in that style - and also that the school isn't afraid to have their students see what other schools do, that the school encourages their students to go out and test what they've learned and see if it works. Now, it could be that the style itself isn't very effective and the competitions for it are easy, but that's a different issue.
