I think this is about right, though online forums are usually slightly N-biased.
IxTx is very common for aspies. S/N is a funny things for us. Aspies tend to be divided into those of us who are ultra aware of our surroundings, and those of us who totally detach ourselves from the outer world. The latter tend to take the characteristics of the intuitive, except that intuitive aspies will still have some trouble with interpretations of things, especially with the whole literal vs. non-literal thing.
Another thing I have noticed with aspies is that the cognitive processes don't make sense at all for some of us. For example,
having Aspergers makes it pretty difficult to have strong Ni, and almost impossible to have strong Fe, but any type other than INTJ or INFJ might not make sense at all.
P/J is another story which I shall tackle later
