Yes, but your current method seems to lack consistency (at least to me).
In some cases, (script fn "somefn();") means script with attributes, in others it means that it has a body. The difference is where the (script ...) is located; at the car of a list or not. Personally, I like the consistency provided by "anything that's not an @ list is body" which means that you don't have to pay as much attention to the number and layering of parens.
