You should probably consult the psychiatrist who administered the test. If you know the source of any given IQ test you take and do not know how to interpret it, you should contact whoever administers it. We, obviously, cannot tell you the name of any given IQ test (as if we would know). With all due respect, if you believe you have dyspraxia, you should have a talk with your doctor/psychiatrist to diagnose whether or not you really have it. Now, I take it you have done just that since, based on what you have said, you took "professional" IQ tests. If this is so, the psychiatrist who administered the test in person should be able to answer your question. Lets be blunt, unless there is someone here who knows the statistics for the specific test you have taken (the name of which we have no clue), then we are unable to answer that part of your question, regrettably.
Also, a comment on what SquareRobot said: ACTs or SATs will not be able to help in proving anything. They are merely college placement tests and in most cases, the questions on them are not a test of common sense or IQ. I know some very intelligent people who have not scored in the top percentile of these tests. These tests may tell him his percentage above a population, but of a population of students (since the majority of people taking this test are students).
