Yep, in normal playing cards, the king is higher, and the ace higher than the king.
In Tarot, however, I do not think one is above the other. What I believe is that the queens know how to enjoy and live according to the traits of their respective suits: they incarnate these traits, in a way. While the kings tend to portray the suit in action: the results one can get wen applying the suit's advantages (and sometimes its disadvantages as well). Just as the page is still coming to terms with the just discovered abilities and the knight gets a bit carried away by them.
That is only one way to look at it, though. I hope you get some more opinions on the subject
