The perk values are available in the hangar in the ENY and OBJ columns. I am not sure what you mean by "Scoring values".
From the help web page:
If you are flying a fighter with an ENY value of 8 and you score a kill on a vehicle with an ENY value of 2, you would receive (8/2) = 4 fighter perk points.
Had the vehicle driver scored the kill on you, he would receive (2/8) = 0.25 vehicle perk points.
A bomber with an OBJ value of 8 who destroys a bunker with a point value of 20 would receive (8/20) = 0.4 bomber perk points.
