Nathan,
In case this might give you a laugh and brighten your day, here's my example
hack for using the RotoPaint node to reorder a list. My plan was to use it with
a callback to update some merge layers. Essentially being able to drag-reorder
layers a la Photoshop! (Why not?) ;^)
I didn't end up using it on this project (yet), but I may find a use for it in
the future. Maybe I'll have some time to learn more about PySide, though, and
code a more elegant solution. 8^)

import nuke.rotopaint as rp
#### Start with your list go items to be sorted...
list_o_layers = ['one', 'two', 'three', 'four', 'five']
#### Create a named RotoPaint node and get it by name (which might be
different)...
rpNode = nuke.toNode('RotoPaint1')
#### Get the curves knob in the node...
cKnob= rpNode['curves']
#### Make a dummy paint stroke to hold each name, so we can reorder them with
the GUI...
#### Iterate through the list of names and create a stroke for each.
for s in list_o_layers:
stroke = rp.Stroke(cKnob)
stroke.name = s
print s
cKnob.rootLayer.append(stroke)

###############################################
#### DO YOUR MANUAL REORDERING, then run the rest...
###############################################
###############################################
###############################################
#### PART 2 -- Run this after reordering the list.
###############################################
#### Get the list of items in the (manually reordered) list...
root = cKnob.rootLayer
for shape in root:
print shape.name
