Applying to Engineering with low ACT Math score

I’m planning on applying to Vanderbilt this fall, and my ACT math score is only a 30. All my other scores are really good… However I want to go into their engineering school (Chemical Engineering) and I feel that in the admissions process they may take that score in the wrong way. My science score is a 36, should I apply as a chemistry major and transfer to the engineering school? Anyone have any advice?
