When I said "restore from backup" I meant that surely in 5 years, if these bookmarks are so important that even having them in the wrong order would mess you up, and you're here so you're obviously a programmer and have irreplaceable source code lying around, you've backed up your registry, app settings, and files at some point, or at the very least set a restore point in XP. So now it's time to use that backup or restore point.
