Historically I think its due to program changes being controlled from 
hardware though number selection (e.g. my Yamaha keyboard used 1 ~ 128). 
Most controllers would usually be controlled by hardware (pedals, 
wheels, knobs) and therefore on a keyboard you wouldn't usually input a 
controller change numerically as a number.
