P.A.S. - While we don't have an ASD diagnosis, my DS sure sounds like yours!
Fun fact - we had just gotten the dyslexia/dysgraphia diagnosis when DS suddenly clicked with phonics. About the same time, letter and number reversals virtually disappeared.
At this point, I don't know what he's "got" (if these things are something you "have" rather something you "are"). But we're just sort of following treatment methodologies for dyslexia and general scaffolding for all the things that PG kids present that look like SPD/ADHD/ASD, etc.
Good luck to you. Bet he's going to turn out just fine!
