Author, Year, sort order for assigning letters a, b, etc.

There was an earlier post wonding the same thing, but the same poster declared that solution for assignment order of letters a, b, c, etc, for same author and year citations was to cite them in the document in the order that you want the letters assigned. 

I have found that not to be the case.  I’ve tried various sort order settings, but have not found the solution.

Could you explain why not? Also are you using the correct output style as changes are saved to a new file (with the word “Copy” added to the filename) so you need to adjust MS Word/EndNote to use the new output style.
