The trick is to put a "0" in front of your numbers (names).
01
02
03
or
001
002
003
if you are going to have more than 99 zones.
Technically Archicad is sorting the names correctly in alphabetical order.
It is not recognising the number in your name as a separate number - so does not list them numerically.
