Definitely. I had to pass a triple challenge recently, and the rule of "best 2 out of 3" was not in play! :P Even though I repeatedly succeeded at the first two stat challenges (Watchful & Persuasive, I think), I also repeatedly failed at the third luck challenge; the game counted a single challenge failure as a complete action failure.
