What is the best way to perform an update of the Owner field on a large number of scripts? I want to make myself the owner of all of our scripts because the former admin of our account left the company. And we have the scripts set up to notify the owner when a failure occurs, so I want to make sure I'm aware of all of the errors. But I don't see Scripts as an option in the csv import process. Is there another way to update this information en masse? Does a Mass Update need to be used? We have about 200 scripts.

Map/Reduce with a record.load is about the only way you can do it.
