I haven't gotten much into scripting for quests, but you might have to link it to a quest alias (the scripting things for quests) to have it set as permanent. I would reference this mod's (http://www.nexusmods.com/fallout4/mods/14966/?) scripts for what you're looking for.

http://www.creationkit.com/fallout4/index.php?title=Persistence_(Papyrus) Unless you have a script that uses that object from anywhere in the game it's better to leave it temporary. Persistent just means that the game always loads it, which can cause really long loading screens and such.

I'll try and help you.
