Hello again Chris, and welcome to a magificent site! I've learned much here.
I must have missed the exchange, but I guess I'd like to ask for a definition of "orderly". Is there a universal sense in which to use this word, or is it a perception? The view from physics is that the idea of order arises from the state of lowest potential energy. If the universe is indeed cyclic, waxing and waning through implosion and explosion, then I have to argue that we are continuing into disorder as the universe expands (but you'll have to accept that well-evidenced axiom first). This is in accordance with the 2nd Law of Thermodynamics; the universe as a whole is experiencing a continuously decreasing energy density. As a finite and static quantity of energy spreads into the larger and larger volume, the higher and higher entropy becomes............ from the perspective of science.
