Well, it depends on the definition of "high functioning", which I think, for the large part, can be subjective. Unless someone is using a formal scale to assess someone's functioning, like the Global Assessment of Functioning.
Asperger's, like all ASDs, can cause some pretty uneven skill distributions in people, so it wouldn't surprise me that a person who appears high-functioning in certain areas also have difficulties in others. For instance, I'm good with writing but I'm shocking at reading maps [I get lost easily], I'm a university student but I can't tell left from right, etc.
