Thank for the response - I appreciate your help and time!
Your solution did not entirely meet my needs. Let me try to better explain what I am after.
I have my Top N parameter set to Top 10, and when I select to sort Fiscal Year and Period2 column by period 2015012 - I get the below incorrect result.
What I expect
These are the Global DUNS that I would expect to see in the graph above when I sort on 2015012.
Any ideas on how to fix the attached?

Not sure if I understand your "challenge" correct.
I can "manually" sort each column (2015007, 2015010, 2015011,2015012) by clicking the header and selecting the "Sort ascending" or "Sort descending" Icon in the textmenu.
The calculation field "Global DUNS Display" can only be sorted based on "Data source order" or Manual
