I doubt it. I'll preface this by saying I don't actually know an enormous amount about Asperger's syndrome, but I know it involves significant difficulties with social interactions and understanding.
Our species, in fact all the smartest species, are smart because high intelligence is needed comprehend the complex social relationships in highly social animals. Now of course this isn't to say having bad social skills is a mark of low intelligence. As we all know people with aspergers are often highly intelligent. Just that in the evolutionary sense, the long term survival of our species requires that we BETTER understand each other. We need to improve our ability to empathize with and understand each others motivations. And for our species especially, having poor social skills is a severe handicap, not only for reproduction but much much more. You won't be the next step in evolution if the step makes it less likely that you'll attract members of the opposite sex for mating.
I agree with mysterie, it might help if you provide some additional reasoning for why you think people with aspergers might have an advantage in evolutionary fitness over the current average person.
