October ACT

I applied to Stanford for REA and it says October ACT scores might not reach them in time. Thus, I don’t want them to wait for my scores in case it did not come out on time and they defer me since they had not received a complete file. So I did not put them on my commonapp as an expected sitting ( I submitted the app after I took the ACT - so it wasn’t an expected sitting). But it did come out on time. Surprise surprise ACT actually didnt take 2 month this time since last time ACT took two month to process their scores due to some delay on ACT’s half. So now I have my October scores and its better than my September.

So should I send it to them or not? I am afraid I do that the admission officer will say that this kid is dishonest and did not report the October ACT on his commonapp even tho on their website it says October ACT might not reach them in time for consideration? Should I still submit?
