Well, if the vhd image is stock (i.e. nothing installed yet) -- it should automatically pick up the new scripts -- when you go to start your installation. But if you want to manually run the Update script in the "Maemo_Install" root directory; which does a force svn update to the scripts you can first. It should update two scripts, install two scripts (new final scripts) and delete two scripts (old beta scripts).
