I don't remember exactly where, but it was Kevin's idea.
Was it on a talk page, or in an edit summary?
Why would trivia go before related enchants? o_O In my opinion trivia should be before the references section but after everything else. But it's not that important.
I think the related enchants section was added long after the trivia section, and since the controversy about trivia was kinda gone, nobody was paying enough attention to fix that arrangement. People who added trivia later probably put it before enchants only to keep the order consistent with the of other pages since they weren't sure/didn't remember/didn't know about the original plan.
