Given that Apple axed the position in charge of Mac automation tech (AppleScript, Automator, System Services, Apple Events, etc) last November, I can't help being pessimistic. Updates to products in the iWork suite repeatedly dumbed down their scripting support, and it's pretty clearly not been a priority for Apple in a long while.
