SAT Subject Tests: To report or not to report?

I took the SAT Subject Tests in June last school year in Math Level 2 and Biology E (got a 710 and 650, respectively), and because of my mediocre scores will retake them next month. I am applying early action to Stanford, and said that I took these tests but did not report the scores yet. Should I put them, or one of them, anyways? Or wait until I retake the tests?
