I have new findings.
Please take a look on this example:

Did you know that  _GUICtrlListView_InsertItem() acts differently for ListView with _GUICtrlListView_EnableGroupView($idListview, True) ?
 

Is it strange for you ?

Conclusion:
After adding new items to a Grouped ListView,
To maintain the correct order of items within a group, it is often necessary to regroup the items within the group by removing the item's group assignment and then reassigning it to the group.

EDIT:
Please let me know if I am wrong about any technical details or linguistic aspects of the conclusion.
I used Google Translate because I am not a native English speaker.
