What's the difference between a commentary presented in text form and a trivia track?

"Commentary" text subtitles are for when an Audio or Video Commentary have optional subtitles which play for what's spoken during the commentary track(s). Many Sony releases have these as set-up options, sometimes for several different languages. Some releases have them, but they must be manually chosen...usually the 2nd or 3rd English subtitle on the disc.

"Trivia" text subtitles will play facts, quotes, etc.. when the movie plays. But not all "Trivia" options on discs play as subtitles. If they are a Trivia subtitle, they can usually be turned on/off with the subtitle button.
