it's not so hard to interface that but we need to pick up the current value

     \ctxlua{tex.sprint(languages.numbers[1])}

however, tex does not privide access to the current language so i'd have 
to introduce an extra counter at the tex end

anyhow, for the moment you can use

languages.numbers[tex.count.mainlanguagenumber]

which probably gives you wat you want: en
