There is no such thing as "GSC scripting". .GSC is a file format. Not a language. It's as ridiculous to refer to "GSC Scripting" as it is to refer to "ZIP Scripting".
The language used in COD scripting is usually referred to as COD Script. Certainly, the developers of COD refer to it that way.
Other than that, good luck with your project.
BTW - if you ever wondered what G.S.C. means, it is the initials of Grant Stuart Collier, former President of Infinity Ward. This was told to me directly by Grant, the first time I met him in person.
