The SAT and ACT folks wait until all the tests of a certain date are completed, scored, and tabulated. They then "burn them" onto a "golden DVD" and send them to the universities, colleges, SA's, etc. Once that arrives, then admissions does their thing and will upload everything they receive. It may take a few weeks after you receive your scores, don't worry about it.
My advice to any candidate, not a pre-candidate, is to send a copy of their scores to their USAFA counselor the minute they receive them with an email "I just wanted to let you know I did this!!" It will make a positive impression and they may even load them from that (and confirm them later).
