I don't know much about TeX macros, but I'd rather use lua here.
For example, this macro will switch direction based on the current text
direction. Not exactly what you are doing, but shows some of LuaTeX's


  if tex.textdir == "TLT" then
    tex.print("{".."\luaescapestring{\textdir TRT}".."#1".."}")
  elseif tex.textdir == "TRT" then
    tex.print("{".."\luaescapestring{\textdir TLT}".."#1".."}")
    texio.write_nl("I don't know how to deal with "..tex.textdir.."

Hello |World| of wonders!
\textdir TRT
Hello |World| of wonders!
\textdir TLB
Hello |World| of wonders!
