You want to sort tag list by label name, right?

Using .map() and lambda you should be able to have a list tuples (id,
label) in tag_labels. From now, I assume you have something like:

  tag_labels=[(3, 'B'), (1, 'A')]

>
>         tag_labels = o

Why don't you apply your .sort() directly on tag_labels? Something like:

   tag_labels.sort(lambda x,y:cmp(x[1],y[1]))

That gives:
  >>> tag_labels
     [(1, 'A'), (3, 'B')]

I hope it helps,
