Should I delete my ACT score?

I’m a senior this year applying to Stanford and my SAT is 1560 but I got a 30 on the ACT without essay. On Stanford’s website it says they focus on the highest composite, english, and writing ACT scores. They also require to send all ACT and SAT scores and require the SAT with essay or ACT with essay. What made my ACT score lower was a 26 in science. I got a 32 on the english section which is better but still not where I’d like it to be. I can’t sign up to take the ACT before early admissions but I do have time to delete the score if need be. Should I keep the score and hope that they don’t focus on the ACT score too much or delete the score but have them wondering why I didn’t take the ACT? Also, I already checked, the ACT score is not on my transcript.
