Quoting Babycakez & Lil J:" Interesting. Maybe he does have OCD or something like that. I noticed he does like to line up his toys ... [snip!] ... like to line up his toys in a row and if you move one or mess up the order he gets upset. I just thought it was normal though."
Those can both be signs of autism (not that I'm saying he has it!) but if you think the avoidance of the messes or the fits if you mess with his order are cause for concern, it's worth getting checked out.
For the record, my 4 yr old has autism and never did either of those things, his was more speech, but IF it is autism or sensory processing disorder, or anything like that, you aren't going to be able to make him "like" doing it or not freak out about it.
Google MCHAT - it's a screening tool for toddlers with autism, might help you narrow that out of the equation anyway
