Yes, just like a ball rolling down a hill qualifies as an optimizing system, a table with with billiard balls qualifies as an optimizing system in the sense that you point out.
Both of these examples also seem like increases in entropy if you consider the full system.
With a fixed amount of energy, there are a tiny number of ways to use it to make the ball move (or to spend energy putting it somewhere other than the bottom of the hill) but an exponentially vast number of ways to use it to increase the temperature of the billiard ball and table (since there are billions of billions of microscopic degrees of freedom that could be vibrating or whatever).
