ACT Subscores -- How Important Are They?

Are ACT subscores weighed heavily when applying to colleges or is only the composite score considered? I consistently score high in reading and english on standardized tests (36 for reading and 34 for english on the ACT/ 730 on the SAT), but fall short when it comes to math and science (24 for both on the ACT/ 600 for math on the SAT). Overall I scored a 30 on the ACT. Will colleges frown upon this discrepancy? I’m applying with the intent of majoring in political science.
