Hello to you oh wise monks at the gates of the Na Pali temple!

I have a fairly simple %hash: UserName => score

eg:

Bob - 10
Alice - 12
Mike - 11
... and so on.

I'd like to output it like this: 
1. UserName - score
2. Another UserName - score
...

reverse sorted by user's tally obviously.

But there's a catch - what I need is to group the users with the same tally on a single row like this:

...
2. Alec - 14
3-5. Sarah, Jacob, Donny - 13
6. Alice - 12
...

What would be the most appropriate way to go about?

Thank you in advance
