Would a 680 on SAT II US History hurt my application?

I received my Subject SAT scores and saw that I got a 680 on US History. My Chemistry score was a 760 so it's not as bad. I also want to take the Literature and Math Subject Tests in October. I'm quite confident about Math but I'm not sure about Lit...I want to major in Chemistry, Biology, or Pre-med (overall the science fields) I plan to apply for Emory and Rice University so would this 680 in USH hurt me? Retaking would be inconvenient in my schedule but if I really have to I will. And is it possible if I choose to send all my other 3 scores and not send USH?
