sort different fields in a report

[mikarsen]

I would just like to ask if it is possible to sort the values of different fields in a report. For example I have three fields that contains percentage values percent1=100%, percent2=65%, and percent3=85%.

I would like to arrange the values from highest to lowest...
desired output would be:

percent1=100%
percent3=85%
percent2=65%

many thanks.
