This is an excerpt of texmf.cnf in TL-2010:
-------------------------------------------------------
% Lua needs to look in TEXINPUTS for lua scripts distributed with packages.
LUAINPUTS = .;$TEXMF/scripts/{$progname,$engine,}/{lua,}//;$TEXINPUTS
-------------------------------------------------------

You can also look where the ConTeXt Lua scripts are.  I think that

  $TEXMF/scripts/pgf/

is a good choice.

According to the setting of LUAINPUTS, only files in $TEXMF/scripts
are found.  I wouldn't try to put it anywhere else.  I don't know the
internals of kpathsea, but I suppose that a file of a particular type
is found most rapidly if it is in a sub-tree which only contains files
of this type.

PS.:  I just ran "cvs update" but I don't see any .lua scripts.  Are
      you working on the arithmetic code ATM?  That would be great.
