You don't need any boot script - there is an easier way.
You must install XP (boot sector of HDD with Vista boot loader will be replaced with the XP one). Now you're unable to boot Vista, but can boot XP. After installing and tuning up your XP you must boot from Vista DVD and choose a repair option to write Vista's boot sector on HDD again. After this you will be able to boot Vista, but will not be able to boot XP.
Next step is to write in "boot.ini" the path to your XP directory in the same way as path to Vista is written there - use it as template.
It's much better for you to install XP on non-Vista partition.
