The Schools will say whatever is convenient for them to protect them from lawsuits…as they also put in a lots of kids who do not have too many APs (may be athletics, legacies, development cases etc.) as well as many kids from small towns where the school does not offer a lot of AP classes. They want to see whether you are challenging yourself or not compared to other kids in your school/area.
The common app allows upto 5 awards to list and the only reason I will not put it if I have something better to list…for example Noble Prize, Intel/Siemens Awards, Olympic Medals etc.,
