no, for this you dont need any scripts. you dont have to run the installer. copy the folder from your current installation to the oem folder and you're done. as long as you have LS up and running on your pc now from the installer, then it will work fine if you just copy the folder over. you dont want to use any other reg keys if you're making an unattended cd. the reg keys from the installer are for specific users and you dont want that setup if you're doing this unattended. all of the LS settings are in its own directory. you only need the one reg key i wrote here.

if you've read and understand the unattended section of msfn, then you know how to make a custom reg file to run, and you know that the oem folder will work as i've said.
