Actually, this should be a smidge better:

    def compare(self, item, column, ascending):
        a = self.text(column)
        b = item.text(column)
        try:
            a = int(str(a))
        except (ValueError, ):
            pass
        try:
            b = int(str(b))
        except:
            pass
        return cmp(a, b)

With this one, you'll only pay for the call to text() once, even if the value 
can't be converted to an int.
