Must I submit test results for all tests if school requires only two but wants to see "all scores"

AFAIK, Georgetown and Cornell are the only 2 US colleges that require all Subject Test scores. Georgetown’s message is clear:

In their case, all means all.

Cornell seems to be more ambiguous; this is a clear case where the applicant should contact Cornell to confirm their requirements and not leave it to other peoples’ interpretations.

All other US colleges (again applicant should confirm) that require all ACT or SAT 1 scores allow the app,icant to pick and choose which Subject Test scores to send.
