Don't strictly sort the population for culling or else you end up with depth-first searching that is highly prone local minima. I try to model selection on natural processes, hoping for some serendipity. Here's my favorite:
Roulette select three members from the population, with chances directly proportional to their individual scores.
Roulette select one member from the three, with chances inversely proportional to their individual scores.
Cull the member selected in #2.
Breed the two members selected in #1 that were not selected in #2.
Return the new member to the population.
I call it Love Triangle Selection ;)
