As I only need the first result presented I didn't favor os.walk, yet
tried it anyway. Below both versions:

1.
aliaspath = mk_alias(path)
directories = mk_pathlist(aliaspath)
files = []

content = os.listdir(path)
content.sort()
for item in content:
    fullpath = os.path.join(path, item)
    if os.path.isdir(fullpath):
        directories.append((item, mk_aliasURL(fullpath)))
    else:
        files.append((item, mk_aliasURL(fullpath)))

2.
content = list(os.walk(path).next())
content[0] = mk_alias(content[0])
directories = mk_pathlist(content[0])
directories.extend([(item, mkURL(os.path.join(content[0], item))) for
item in content[1]])
files = [(item, mkURL(os.path.join(content[0], item))) for item in content[2]]


And both with the same output:

 Path
c:\Python25\Lib\site-packages\pygame\examples\macosx\aliens_app_example

 AliasPath
Audio\site-packages\pygame\examples\macosx\aliens_app_example
