Have you read the docs about set_justify()? It has 3 important parts in 
your case.
Quote [1]:
|gtk.JUSTIFY_LEFT| is the default value when the widget is first 
created. If you want to set the alignment of the label as a whole, use 
the |gtk.Misc.set_alignment|() 
<http://library.gnome.org/devel/pygtk/stable/class-gtkmisc.html#method-gtkmisc--set-alignment> 
method instead. The |set_justify|() 
<http://library.gnome.org/devel/pygtk/stable/class-gtklabel.html#method-gtklabel--set-justify> 
has no effect on labels containing only a single line.

  * Your call to set_justify() does nothing, because you call the 
default value.
  * It wouldn't work anyway because you only have one line.
  * The solution is to use set_alignment()

So replace label.set_justify(gtk.JUSTIFY_LEFT) with 
label.set_alignment(0, .5) and it should work.

Cheers,
Timo
