As a one-liner, you can also deconstruct and rebuild the outline numbers:
new_outline = ['.'.join(v) for v in (sorted([k.split('.') for k in
old_outline]))]

For 2.4 and beyond: (using a key function)
def numparts(outlinetext):
return [int(number) for number in outlinetext.split('.')]
lst = ['1', '1.2', '1.12', '1.1', '3.1']
