i have to wait til there is a windows binary, but looking at the txt 
file, why this syntax?

Each script file must start with a special header. The header must start 
with

{{{
--[[TeXworksScript
}}}
followed by a number of
{{{
key: value
}}}
pairs and finished off by the line
{{{
]]
}}}

why not just create a texworks table

texworks = {
    key1 = value1,
    key2 = value2,
}

after loading the script, the lua instance in texworks can check this 
table (no parsing of the lua file needed)

apart from this better fitting in the lua syntax than {{{ }}} it also 
makes syntax checking easier when writing scripts
