Is it possible to change the order of objects in a group? Simply put, is it possible to change the order of objects in a group?

I would like to change it due to using  the Animation Nodes addon effecting objects in an undesired order.

In the provided GIF, you can see that one block in the bottom left scales up at the end instead of near the beginning or so. 



The Blend File:
You can sort the group (actually any list type) by using Sort List node:



Tip: You can apply multiple/cascading sorting rules to a list. For example, in my case , I first sorted all objects based on their Y location, then sorted the result again by X location.



Update:

You can try applying round math here for better sorting, due to the precision, for example:

round(e.location.y, 3)

round(e.location.x, 3)
