Those are excellent scores to be sure. Mensa will accept them. I don't think they are so rare, and I didn't understand why the media made such a fuss about the 4 year old too. My son at 6 (he wasn't tested earlier) got on the RIAS: Verbal 147, nonverbal 174, total 165. (All >99th%). I mailed them to Mensa and they accepted him.
