Have his IQ scores been reviewed for a non-verbal learning disability? My daugther (age 16) has a NVLD, and has always very strong verbally, especially in speaking. She has also been considered "borderline Aspergers" -- some psychologists she has seen for testing have commented that they think she is, others have said specifically that they don't think so. We have not had her formally tested for Aspergers, though. She had some of the same issues your son does; her handwriting is still terrible and slow. She hates loud noises and crowds, she didn't have close friends until about the age of 10, and definitely had obsessions.
So although he may not have Aspergers, it may not just be his high IQ that is causing his difficulties.
