Oh yay, congratulations!! That's excellent! And high scores across all 3 sections, too.
I would rely more on what MBAMission thinks vs. me (admissions is not my area of expertise), but I don't think it could hurt. Either they'll just use the highest score or they'll view a progression positively, in which case the lower score shows that you stuck with it over the summer and lifted not just some scores but all of them.
Good luck with your applications!
