Hi, welcome here. I havew Asperger's, but I do meet the B criteria and actually have more trouble in that area than in the social area. The thing is, you need only one feature from the B criteria in order to have AS (I have two with no doubt and one I'm not sure), so even if you have relatively little problems with routines/special interests/stimming, you may still be an Aspie.
However, actually, it doesn't really matter whther you are AS or PDD. PDD is really a garbage can of everyone who isn't exactly either autistic or AS but who does have autistic-like problems. Some clinicians aren't even diagnosing AS/PDD/HFA in adults but will just giv eyou an ASD (autistic spectrum disorder) label.
