Execution4 vs 1
Portal leans clearly harder on execution.
Portal
Portal placement timing modest.
SimCity 3000
Point-and-click planning; pause anytime.
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Portal

SimCity 3000
No adversary exists.
Variance0 vs 2
SimCity 3000 leans clearly harder on variance.
Portal
Deterministic chambers; no randomness.
SimCity 3000
Random disasters and neighbor deal timing.
Optimization8 vs 9
SimCity 3000 leans a little harder on optimization, though the gap is small.
Portal
Pure puzzle-solving optimization.
SimCity 3000
Land value, utilities, and ordinance math reward pure system mastery.
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.
