Vlookup - Finding additional values from duplicates using an additional column

I am using a spreadsheet as a score sheet for a competition. One of the columns is the student's GPA. After entering all the scores there are duplicate final scores. I need a way to have it look at the final score and then use the GPA so that it will not put a duplicate value in the final column.

Column N is the Total Column, Column O has the Names that correspond to the Total Column. Currently I am taking this total and putting it into Column Q (High Scores) in high to low order. Column R should have the names that match the scores. But with duplicate scores, it is only putting the first name associated with the score. I would like to use the GPA as a final determining factor for the duplicate scores. The higher GPA would come before a lower GPA. I have tried to put an additional column to bring the GPA over to correspond with the High Scores Column, but could not get it to work.

There are actually more names for the competition and the top 10 will be moved to a different sheet and further judged.

I have attached a sample with the exact formulas that I am using.
