Talk to the judge, and ask him why he's giving you low scores. Then take a look at the stuff you have in your inventory (look at them all individually by pressing the "L" key), and see if any of them could be of interest to the judge. If not, go to other places on the island and try to pick up everything you can, and look at them after you pick them up. There's something on the island that will make him give you a better score.
