gscopes need to be applied on the component collection as they are applied as part of the index build. They will have no effect if defined on a meta collection.
It is generally not a good idea to have so many component collections - you lose ranking information when web collections are split up, the can be much harder to manage and also risk having duplicate URLs in the search index. Have you thought about using a web collection with multiple profiles instead?
I also have a feeling that meta collections are limited to a maximum of 64 component collections though I believe you receive an error when you reach the limit.
If you must reference the gscopes config from the meta collection you could copy this in to your component collection using pre-index workflow as part of it’s collection update. However note that this may not work in future versions if the way configuration for gscopes is handled changes.
