Excel 2007 : Using INDEX and MATCH (or other) to return cell based on largest associated value

Hi,

I am having trouble with using INDEX and MATCH (open to using other formulae too) to tell me the cell based on the largest value in a table.

My WIP formula:
=INDEX(Score!A3:AU813,MATCH(LARGE(Score!B3:AU813,1),Score!A:A,0),MATCH(J2,Score!B1:AU1,0))
I think the problem is there, though I am not sure about that.

Basically I want to find the highest value in a single column between Score!B3 and Score!AU813 with the column based off Output!J2 (current sheet) and give me the cell value of Score!A3:A813.

Example, I enter 73 for J2 in the Output sheet and it should use column AN in the Score sheet to check for the largest value (ignoring the first 2 rows which are background codes) and return the row of that largest value and use the value in column A of that row as the result.

As it is possible to have multiple same largest values, how would I handle those best on my Output sheet? I am looking at the 5 largest values so I guess there is room for 5 same top values. So on the Output sheet is it possible to add a handler to the 2nd-5th row under "Outcome" to ignore/skip the value of the fields above?

Example: If A6 = A5, go to next highest value in the score sheet and give me that instead.
