It does work using require.

% mkdir -p ~/texmf/scripts/lua/foo/bar/
% echo 'texio.write_nl "HELLO"' > ~/texmf/scripts/lua/foo/bar/baz.lua
% echo -E '\directlua{require "foo.bar.baz"}\end' > test.tex
% luatex test.tex
This is LuaTeX, Version beta-0.70.2-2012052410 (TeX Live 2012)
 restricted \write18 enabled.
(./test.tex
HELLO )
No pages of output.
Transcript written on test.log.

This was added by revision 3558, first released with luatex 0.60, in april 2010.

IIRC, luatexbase-loader has such an implementation.

@Heiko: Unless I'm mistaken, luatex-loader.sty, as well as
luatexbase-loader.sty, should be useless with recent versions of LuaTeX.
