The create/modify/delete "action" is applied at the node/way/relation level. There is no way of applying changes at a tag level. When osmosis receives a modified entity in the --apply-change task, it replaces the existing entity with the new one.
So in other words if you wish to add tags you need to include all existing tags in your modified entry.
