Could you consider changing sort to allow any callable object:

    static int sort (lua_State *L) {
      int n = aux_getn(L, 1);
      luaL_checkstack(L, 40, "");  /* assume array is smaller than 2^40 */
   -  if (!lua_isnoneornil(L, 2))  /* is there a 2nd argument? */
   -    luaL_checktype(L, 2, LUA_TFUNCTION);
      lua_settop(L, 2);  /* make sure there is two arguments */
      auxsort(L, 1, n);
      return 0;

This is consistent with pcall, xpcall, for, package.loader[n], etc.,
all of which accept any callable object.

Discussed here: http://lua-users.org/lists/lua-l/2008-02/msg00405.html
