Question about sending all scores

So I am applying to Carnegie Mellon (definitely a reach school) and this is their policy with scores:
“Applicants are required to submit all official results of either the SAT Reasoning Test/new SAT Test or the ACT Test and those SAT Subject Test results required for the academic program you are applying to.”
The “OR” is what gets me.
The ACT score that I sent was much higher than my SAT score, so can I send only my ACT and SAT subject tests, or do
I have to send my sub-par SAT?
Thanks

I think you can just send the ACT, because of the or. But the best way to find out is to email the admissions office.

Or means OR. Send one set or the other.

Thanks for the help!
