Sort by multiple measures in direct query

Hello,

I am trying to sort the below stacked bar chart so that I get all the Highs and then the Mediums and then the Low. My 'High' is getting sorted correctly. However 'Medium' and 'Low' are not sorted correctly. I would want the bar with 4 highs and 3 mediums display above the the bar with 4 highs and 2 mediums. And so on...

Kindly let me know if this can be done
