You probably just have an unusually spread-out constellation of symptoms. Most of us "emphasize" one part of autism or another, with the primary traits being quite extreme and others perhaps not even present at all. But sooner or later, what with the inherent randomness of the world, there has to be somebody who simply has a large number of traits. That doesn't make your case all that hugely different from others'; it just means you have a large number of traits (and says nothing about severity).
Personally, I think with the AS tests and whatnot, above a certain point the score doesn't really say much about whether or not you have AS; it says more about whether your particular case emphasizes certain traits or else is more even across-the-board. The higher scores just mean you have more traits--though not necessarily more severe ones. Probably not more severe ones, actually, because extreme traits usually come from your brain being structured in a certain way, and tend to exclude other extreme traits because those would require a different structure.
So yeah, I wouldn't think it's any cause for concern. Interesting, maybe.
