You can get 100 points easily without even worrying about the left. Tank the right with the hero Sin, and the entire rest of the party can go to the middle. This is easier because you have only one hero Sin to micro. Just be careful not to let minions aggro foes from the left while your party of 7 fights in the middle (flag your MM toward the right in the little upper pathway leading from the middle to the right).
