Also, did you test through NUMATS? They give a nice report suggesting appropriate coursework based on the test results. My DD's 4th grade scores were similar to yours other than in English, and she got "Consider full grade acceleration, subject area acceleration, early entrance to high school" in every area but Math.
It seems like other people have said that they could provide their test scores to a second talent search group, and for a fee, get access to that search's resources. That report might be something you could use with the school, too.
