To make my argument clearer, here are the actual scores for the top three robots of Series 5, heat H

SUPERNOVA
 * Axe Awe = 3 points
 * Behemoth = 0 points
 * Crushtacean = 3 points
 * Granny's Revenge = 3 points
 * Robochicken = 3 points
 * Wheely Big Cheese = 3 points
 * Wolverine = 2 points
 * Total = 17 points

BEHEMOTH
 * Axe Awe = 3 points
 * Crushtacean = 0 points
 * Granny's Revenge = 3 points
 * Robochicken = 3 points
 * Supernova = 3 points
 * Wheely Big Cheese = 2 points
 * Wolverine = 2 points
 * Total = 16 points

WHEELY BIG CHEESE
 * Axe Awe = 3 points
 * Behemoth = 0 points
 * Crushtacean = 3 points
 * Granny's Revenge = 3 points
 * Robochicken = 3 points
 * Supernova = 0 points
 * Wolverine = 3 points
 * Total = 15 points

So, yeah, Supernova scores the most points, hence why it's ranked at number one. Behemoth and Wheely Big Cheese just didn't score enough points to outrank it.
