So, the grammar itself is very simple: there are orders, which can be
delimited by newlines, commas or semicolons.

There is a 'delayed order' which has a conditiional clause.

So, rather than making a really complicated grammar, use the smallest
possible one, and work with the abstract syntax tree to verify it.

It's _almost_ simple enough to just use Lua patterns, except for the
conditional expressions...
