Civilization V
Random starts, barbarian spawns, and goody huts create hidden unknowns
Portal 2
Puzzles are deterministic with no randomness.
Optimization9 vs 9
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Civilization V
Hex placement, social policies, and victory routing are fully solvable
Portal 2
Solving the puzzle's logic IS the entire game.
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
