Looking at the implementation of Tuple.opCmp, I'm not sure I'd 
bet on existence of opCmp for fundamental types:

        int opCmp(R)(R rhs)
        if (areCompatibleTuples!(typeof(this), R, "<"))
        {
            foreach (i, Unused; Types)
            {
                if (field[i] != rhs.field[i])
                {
                    return field[i] < rhs.field[i] ? -1 : 1;
                }
            }
            return 0;
        }
