Explain what? I think that you are mis-interpreting the entropy concept!

Well, all structure and order requires a strong force (or work) involved...
In your example, the quarters were already in order to start with due to some work involved, so you actually created disorder and not order when you threw them against the wall...
A powerful hurricane or tornado is a better example, the air flow in it is very orderly due to the strong spiral forces involved, but it still creates a lot of disorder when it passes through! So, as you can see order and disorder are very much relative...
The entire solar system is in the milky way galaxy, so it is flowing according to very strong spiral forces (and gravity!) that also give it order. But, if the galaxy (like a tornado or hurricane) is passing thru another large system, it will then bring a lot of disorder to it and vice versa...
