I can reproduce this. As a workaround, you can insert a non-breaking 
space (U+00A0) immediately after the "[[":

     \starttext

     \startLUA
     words = [[
     one
     two
     three
     ]]
     \stopLUA

     \stoptext

(You can't see the NBSP, but it's there)

You can also use the Scite syntax highlighting:

     \usemodule[scite]

     \starttext

     \startLUA
     words = [[
     one
     two
     three
     ]]
     \stopLUA

     \stoptext

It produces different (but usually better) output than the default 
highlighter. This module is installed by default with ConTeXt LMTX.

There's also the Vim module:

     \usemodule[vim]
     \definevimtyping[LUA][syntax=lua]

     \starttext

     \startLUA
     words = [[
     one
     two
     three
     ]]
     \stopLUA

     \stoptext

You would need to install this module manually though.
