I'd be very surprised if those scores didn't get him in. Most public school gifted programs take kids with full scale scores in the 98th percentile (130 approx. depending on the std deviation of the test) and quite a few take kids in the 95th percentile (which is usually in the mid 120s). There is one school in Portland, with which I am familiar, that is billed as being for highly gifted kids and its cut-off is at the 99th percentile. Your son would still make that.
