I believe, it is safer to define `org-babel-variable-assignments:screen' 
some way: alias, substitution, function that calls 
`org-babel-variable-assignments:shell'. I am unsure which variant is 
better. I see a couple of callers for specific language in ob-core.el.

I can not suggest anything specific concerning sh vs. bash. I have never 
tried to pass tables to sh src blocks.
