For a project in one of my earlier companies, I used SPARK[1] to write a
little parser for a language of my own making to used to specify some
conditionals. 

The parser would convert this into a python expression which could be
evaluated with some objects to return a true or a false. 

If you have the grammar of your source language at hand, it's a fews
hours job to write a parser for it using SPARK. Once you do that, you
have to write a backend to convert it into LUA which might be a little
more complex but not impossibly so.
