IQ scores don't mean too much, especially when they come from tests that don't take into account someones disabilities. Even when they are administered by a person, they don't tell much. You could be smartest person with regards to math, spatial and analytical abilities, but have very poor communication skills and get a 50 because of it.
That said, I've scored as high as 167 on that test. These results are definately inflated, like Doom said, since my "real" IQ isn't that high.
