[copied from roundup-devel e-mail]

It seems that roundup treats the ID of an issue as a 
string and not as a number. The problem then is that 
sorting is wrong, if one wants to sort with respect 
to the issue ID one expects to get e.g.

  1   2   3   4   5   6   7 ...

but at the moment one gets this order:

  1   10   11   12  ...  19   2   20   21  ...

This should be changed I think.
