Should I include my 103.5 AMC12A on my SUMaC application?

I’ve just taken the AMC test and got a 103.5, without much revising. I know that it is bad, and I could have done much better with some revision. But I’ve only known about it a week before and didn’t have much time to revise.
I’m an international student, and I’m also applying for the SUMaC this year. So I’m wondering should I include my AMC score in my application. I’ve got some good achievement in national maths competition, so I afraid putting my AMC score in might reduce my chance of getting in.
So what do you guys think? Should I include it?
