Unfortunately gtk_list_store_reorder() cannot be used by language
bindings, as the pointer value cannot safely be handled by interpreters
(it has neither a defined length nor is NULL TERMINATED). Thus it was
marked as non-introspectable.

I'm afraid there is no quick workaround for this, you need to write a
function which builds a new store in the desired order.

Title:
  gtk_list_store_reorder() is not introspectable

Status in “gtk+3.0” package in Ubuntu:
  Triaged

Bug description:
  gi.overrides.Gtk.ListStore has no attribute .reorder. Porting a PyGTK
  app to GI GTK3, I found that sorting a TreeView is no longer possible
  because GTK.ListStore doesn't provide a .reorder method. Reading the
  source code, I found that pygobject indeed doesn't have any override
  for .reorder. This is the source code I'm talking about:
  http://git.gnome.org/browse/pygobject/tree/gi/overrides/Gtk.py

  This is something I can't fix, but since it's likely that many Python
  GTK apps use TreeViews, it'd be very nice if a wizard could have a
  look at this ASAP.
