You don't put it on your ERAS CV, there won't even be a spot for it. ERAS has a bunch of fields for you to fill in and then it automatically generates a horribly formatted CV for you.
I would however put my scores on the CV for VSAS and for anyone I plan on having me write a letter of recommendation, unless I had low scores. If the scores help you get a rotation, great. If they keep you from getting a rotation, at least you didn't waste your time at a program you couldn't get into anyway. I think giving all the information you can is the best way to go.
