You should be able to insert the Tiger disk and when the window opens showing the Install Mac OS X icon, scroll the window until you see the Optional installs.mpkg.

Graphics that show the steps are in the first link in my previous post.
If that doesn't do the trick you could always use Pacifist but I don't know if they have a free trial.
