Along the sensory line--not just tags but, in my DDs case, corduroy and velvet. Can't stand to touch 'em. Can't stand for other people to touch 'em. I can't even back up my cloth-seated car (you know, turn around with my arm on the passenger seat) without her squealing because the cloth is too fuzzy.
I wondered a little early on, but--like you said--she's just too darned social for me to think it's AS.
My DH is like that with those fabrics - fleece, too. It's a pity, he hates many of my favourite clothes :-( DS seems to be free of that kind of sensory issue, but has plenty of other overexcitabilities.
