I'm currently planning to add a new feature to the CPANTS site: I want the list of 'top' authors to list the previous ranking of an author (like in music charts). Additionally, I want authors with the same average kwalitee listed on the same 'spot' ('ex aequo', as in results of eg downhill skiing)

Are there modules on CPAN that calculate somthing like this?

Given an input like: 

[
  [RUBYKAT,15.97],
  [SAPER,15.78],
  [PETDANCE,15.5],
  [AMBS,15.5],
  [BARBIE,15.45],
   ...
]

[download]
I would like output like this: 
    1: RUBYKAT
  ^ 2: SAPER
    3: PETDANCE
       AMBS
  v 5: BARBIE

[download]
(where ^ and v should be up/down arrows representing a change to the previous status.)

If there isn't a module (or several doing parts of this), I'll probably roll my own. Any naming suggestions?
