I think S stands for Super. then it goes like normal alphabetical order, A, B, C, and D. Or maybe even Special, Supreme. I think it is the same as Yu-Yu Hakusho. I haven't read the manga yet, but I think it is safe to speculate that S class Twilights are unique and very powerful, anyway, I look forward to see more of this great anime.
