I saw what you were doing the moment you mentioned genetic algorithms...remembered the work of Karl Sims, for isntance. I'd never thought of using this to arrive at a solution for a static pose! I'm amazed it runs so quickly, too. As for the sort process at the end of each generation, what about a variation that allows the user to pick instead? Thus a guided evolutionary process (shades of creationism!!) That way user input could train the evolving solution in ways that better suited an artistic goal (such as the elbow height issue you mentioned). This is revolutionary. Almost makes me want to run out and buy Pro-pack.
