@Rich: You are always on the Store View, but you may be on particular one, or default one. If you will use 'website' and will give Website code you will land on specified Website's default store's default Store View. If you will use 'store' and will give Store View code, then you will find yourself on the specified Store View.
As a matter of fact there is also a 'group' type valid, which would lead to default Store View for the Store, and it seems that code you have to provide in this case is the Store's (store_group) id value.
