It will.  I tried also on MikTeX 2.7 and it works there too, so
chances are it will also work on older versions.

In that case I would first check the current directory for the script
and then search with kpsewhich.  I would suggest something like this:

  @setlocal
  @set script=
  @if exist "%~dpn0.lua" set script="%~dpn0.lua"
  @if not defined script for /f "delims=" %%I in ('kpsewhich
--format=texmfscripts %~n0.tlu') do @set script="%%I"
  @if not defined script goto :scriptnotfound
  @texlua %script% %*
  @goto :eof
  :scriptnotfound
  @echo script not found: %~n0.lua 1>&2
  @exit /b 1
