My first proposition was: in B1 formula copied all the way down and used for sorting.
so first Zone Range A and B and Zone Range 1
then Zone Range C and D and Zone Range 1 or Zone Range A and B and Zone Range 2 or Zone Range C and D and Zone Range 1
As I thought it is yur idea from the description.
But then realized that what you've shown in manual result is:
Zone Range A and B with all Zone Range 1 ... nnn in ascending order,
Zone Range C and D with all Zone Range 1 ... nnn in ascending order,
...
for such sequence use in B1 and copy down:
and sort your data on based on this formula
