Maybe you can find such hash table in Lua ;-)  You can add the pairs
"string-key" -> "number->key" into the registry (or another table). Then,
when you enter your tag-method function, you do

  /* assuming that "string-key" is on the top (last parameter) */
  lua_rawget(L, LUA_REGISTRYINDEX);
  number_key = lua_tonumber(L, -1);
