They obviously can't copyright the facts themselves, just the collection. I don't know if it would be sufficient to reorder the questions, but it would be trivial (pun unintended) to reorder the questions keeping the answers in the same order. It would probably also be necessary to fix errors and "changed facts" (I saw a question about the stolen base record holder, answer Lou Brock). There are so many trivia books, I'm sure there is precedent that could be researched.
