Should I send my GRE Bio subject test scores

[KF13]

I took the GRE bio subject test in October and just got the scores back. I knew they wouldn't be great (~60th percentile) because I didn't manage time well and did not finish the test (I did better on Ecol than Organismal and Cellular). Some of the programs I am applying to (ecology-related) recommend the test and others don't. Should I send the sub-par scores (or send with an addendum about not finishing and point to my high grades in upper-level bio courses as proof that I know bio)? Should I send only to those schools that "strongly recommend" or not send at all? I have seen some contradicting advice here in the past. Thanks.
