Should I send in both?

For my first ACT, I scored 31 (English 31, Math 30, Reading 30, [Science 32, Writing 29]) but for my second ACT I scored a lower composite score (30, 31, 32, [25, - ]). I know I completely bombed my science for the second ACT, but I got scored a point higher in Math and 2 in Reading. So if schools super score, ( 31, 31, 32, 32, 29) my score would be 32.

My gut says not to send in the second score, because my science is horrible and I would like to major in a science. Also, schools seem to dislike inconsistency.

It would be great to have a second opinion though.
