In MOSS 2007, how to sort a list by a total/aggregate?

Question

I have a basic issue tracking list with a few columns, let's say Application, Title, Created By, and Task Priority.

My list is grouped by Application and I am performing a Total (Average) on Task Priority, so the view with some data looks like:

        Title                                                         Created By        Task Priority

---

Example Application                                               Average = 5.0

1. Fix bug when user logs in                           pandincus            3.0
2. Why are there duplicate people?                pandincus            7.0

Other Application                                                    Average = 1.5

1. Runs slow at 3:00 PM daily                         pandincus            1.0
2. Add new column for vacation days             pandincus            2.0

The above works fine. However, I'd like to be able to sort by the average task priority. Currently, I cannot find any way to do this, since the 'group' sorting takes precedence.

Is it possible, either using the SharePoint site or by using SharePoint Designer, to sort the groups based on the average task priority?

Answer 1

If you convert that view to a data view web part in Sharepoint Designer, you can build your own sorting logic and you should be able to sort by the nodeset average.
