figureofwrit, you're probably wise to just let it go, in case something weird happens during your challenge of the question. (It's unlikely, but I suppose that it's possible that you made a lucky guess, and if the question is invalidated, then maybe it'll drop your score slightly.) And more importantly: congratulations on the 750!!!
But for anybody who isn't thrilled with their verbal score, it might be worthwhile to go through the paperwork of challenging the question.
If any of you challenge the question, let us know how it goes!
