How did the judges agree on Harry’s score in task 2 of the Triwizard Tournament?

I’m not arguing with whether it was right or wrong that Harry got placed second for trying to rescue all the hostages, but why did any of the judges other than Dumbledore and Bagman agree?

Karkaroff hates Harry and gave him an undeserved 4 in the first task.

Madame Maxime is maybe a fairer judge but she also doesn’t want Harry to win, since he was tied first, especially since Fleur came last.

Percy is the ultimate pedantic rule follower and proves again and again that (at this stage) he cares more about what seems proper than the “right” decision. Yes, he’s worried about Ron, but they’re all safe in the end.

I only see Dumbledore (hard favouritism and big believer in morals) and Bagman (so he doesn’t lose his bet) voting to give Harry a better rating, but Bagman says that the judges all agree that this shows moral fibre other than Karkaroff. I don’t really see this fitting in with their characters up until this point.
