Plugin developer these days should be taking into consideration the google minify style. Most plugins I've used and seen tend to be minify safe.
Though Mipey has a good point. If the Scirra arcade is locked from 3rd party plugins. Then it is up Scirra to provide all the basic plugins. MoveTo with DT would be a very basic feature that I think shuold be in basic movement model, not even a plugin.
