Congrats to your DS! Those are great scores, and you can see the percentiles compared to National norms here: http://www.actstudent.org/scores/norms1.html

If he took it through the talent search, did you get these percentiles, or just percentiles as compared to the other talent search participants? I think a 94th percentile in English compared to mostly 17 year olds is much more significant than a 99th percentile (or whatever it is) compared to other 12 year olds.
