@cadffm-I think the "language thing" got us on different tracks.
I'll try to address all your comments:
First, since OP hasn't replied yet, or posted image(s) or "problem" dwg file we are all just guessing on what the actual problem is, or even if there is one, and it wasn't just a "general knowledge" question
My reply was meant to address a (rare) problem I have where an associative hatch "forgets" its own draw order relationship to its own boundary (initially set in hatch creation dialog window) not that a hatched object needs to change draw order in relation to other objects in model space
In this instance the only solution I have found is to dis-associate the hatch, and either re-create the hatch, or the boundary. Or delete and re-create both.
I assumed that OP being a "level-7" member he/she would either already be familiar with properties window, hatch editor, etc. and if not would ask for more details, in which case I would provide as best I could...since I had no idea if I was even addressing the actual issue, I didn't take the time to go "in-depth"
Yes, I am familiar with pickstyle, pickadd, etc. and ctrl+H to quickly turn object grouping on or off, but again, I wasn't even sure if I was trying to answer the actual question. If it was simply how to use draworder command, that was answered by other folks....
Sorry for any misunderstanding or confusion.
