I came looking for another thread in this section and came across this one. As a teacher of autistic children (specifically ones with AS) I interact with these students on a regular basis. When I read The Curious Incident some years ago I remember really loving it because I was able to hear Chris' thoughts. I typed him as an INTX. I have worked with many AS children and three specifically come to mind. One is most definately an INTP and another an INXP, and the third an ISFX. I most definately think that while it is definately difficult to type an Autistic person it is not impossible if they are functioning highly enough.
