Possible to sort custom data type list in a gridview?

I created a custom data type called "cultures" that lives within the "batches" collection. I'd like to display the array of cultures in various orders depending on user input (createdDate, isActive, status, etc).

Is this possible or is the array not sortable? If not seems like I'd be better off creating a separate collection for "cultures".

Thanks as always for any help...
