Close To Twenty

This game is played with cards in HOSTS classrooms all across America. Five cards are dealt out to the player who then chooses the three best cards according to the rules below. Good luck!
4 6 * 6 6

Rules: Select three numbers from the values displayed above. Then press 'Play'. Make your choices such that your three numbers, when added together, come as close to 20 as possible. If your sum comes to 20 exactly, you achieve a perfect score. The farther your sum diverges from 20, the higher the resulting score. For example, a sum of 19 or 21 results in a score of one while a sum of 18 or 22 results in a score of two. The player with the lowest score wins. Asterisks represent wildcard values. No result set will ever contain more than two wild cards.

You are playing against the computer. But this program is designed to always find the combination which results in the lowest score, so you can't actually beat the computer. Your challenge is to not let the computer beat you.
