Keyboard shortcut to jump between tabs on OS X Terminal

Problem

In OS X Terminal.app, if you open new windows, you can easily switch between them with Cmd-1, Cmd-2, Cmd-3, etc. You can also cycle between tabs, using Cmd-Shift-{ and Cmd-Shift-}. (or Cmd-Shift-Left and Cmd-Shift-Right) But is there a way to jump straight to a particular tab, like you can with windows? e.g. Cmd-Shift-3 to jump to the third tab? (That's not it, of course.) I'm pretty sure it's impossible out of the box, but what if I'm willing to write some AppleScript to make this work?
