Sorting Two Ranges In Different Order And Combining Result

I am wanting to display cricket bowling figures - the best figures for each player as the season progresses.

I track runs and wickets each week like this:

Runs 23 25 18 35
Wickets 1 3 2 3

Sorry can't post attachments. Top row is A1:E1. Bottom row is A2:B2.
This shows the bowling figures for 4 weeks.

I need to sort the Wickets range and find the highest number. When there are two or more cells returned with the same value (as there are here (3)), we then need to find the lowest value in the runs range for these two matches.

The result needs to be displayed as follows:

(number of wickets hyphen number of runs)

In this example 3 wickets was found twice. 25 runs were conceded one week and 35 runs another. So the result needs to be: 3-25

When there is only one cell with the highest number of wickets, the number of runs for that week is chosen without any need to check anything else.

e.g.

Runs 23 34 20
Wickets 1 3 2

would return: 3-34
