If you print self.proxy.sortOrder() you'll find out that you're currently
using a descending order, which is why you've to invert the comparison.
I suppose that's due to the default sortIndicatorOrder of the QTreeView
header, which seems to be set to DescendingOrder if the indicator is not
shown.
Just use self.sortByColumn(0, QtCore.Qt.AscendingOrder) and it will work.
