it renders most afflicted persons unsociable and awkward and therefore highly unlikely to pass on their genes?
What makes you think it meakes them any less likely to pass on their genes - on the average? Autism spectrum is virtually synonomous with "nerd". Recent studies (referenced in at least one recent slashdot discussion) have shown that "nerds" are nearly as likely to marry as the average, and MUCH more likely to have a stable, long-lasting, marriage.
While I didn't see anything about their reproduction rate, stable marriages tend to lead, not just to children, but to an upbringing that produces SUCCESSFUL children. (In particular, a male role model is virtually required for the male offspring to avoid mis-socialization that leads to a tendency to violent crime and prison time.)
Add to that the observation that some of the best paying jobs tend to be performed very well by, and dominated by, people with various Ausbergers-spectrum "disorders" and you have obvious advantages for both attracting a mate to a stable relationship and providing children with competitive advantages (especially health care and education).
