Great point. Your Field Force Representative or BGO/ALO (depending on Service Academy) is not responsibile for ensuring that your SAT is where your son wants them to be. Guidance from Admissions has always been to submit the best set of SAT Scores since they accept the best set of scores submitted and also Super-Score.
It is one's own responsibility to ensure that their application is competitive and the best they have to offer. Furthermore, average SATs and SAT breakdowns are posted and easily accessible on the West Point Admissions website through a quick search:

I recommend checking out
Extreme Ownership: How U.S. Navy SEALs Lead and Win by Jocko Willink and Leif Babin. Even though I do not think this is the fault of your Field Force Representative and I understand that you may, you will have to realize that in life and in the military, that not everything is fair, but you have to deal with it and take responsibility for everything that you can do.
