I still don't know enough to help you much. It would help if you showed 
some real code and data. How are you storing the names and percentages? 
If you have a list of pairs of (name, percentage) then you should be 
able to sort it directly with the sort() method of the list. For example:

In [3]: data = [ ('Kent', 50), ('Sara', 80), ('Fred', 20) ]
In [4]: data.sort()
In [5]: data
Out[5]: [('Fred', 20), ('Kent', 50), ('Sara', 80)]

Use append() to add more data, then sort again to get it in order:
In [6]: data.append(('Joe', 90))
In [7]: data.sort()
In [8]: data
Out[8]: [('Fred', 20), ('Joe', 90), ('Kent', 50), ('Sara', 80)]

What is a bundle? I don't know of any Python meaning for that term.
