this appears to be working, what where you expecting? 

"An upper case "S" means there is no executable permission, but the set group id function is active- that is, a file in this directory will belong to the same group id as the directory itself."


If the parent directory has the set group id set, the child will as well.
i.e.
dwright at debian:~$ cd /tmp/
dwright at debian:/tmp$ mkdir test
dwright at debian:/tmp$ ls -ld test
drwxr-xr-x 2 dwright dwright 1024 2008-09-04 05:19 test
dwright at debian:/tmp$ ls -la test
drws------  2 dwright dwright 1024 2008-09-04 05:19 .
drwxrwxrwt 13 root    root    3072 2008-09-04 05:19 ..
dwright at debian:/tmp$ chmod 2700 test
dwright at debian:/tmp$ ls -la test
total 4
drwx--S---  2 dwright dwright 1024 2008-09-04 05:19 .
drwxrwxrwt 13 root    root    3072 2008-09-04 05:19 ..

dwright at debian:~$ python
Python 2.4.4 
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.mkdir('/tmp/test/TEST', 0700)

dwright at debian:/tmp$ ls -la test
total 5

drwx--S---  2 dwright dwright 1024 2008-09-04 05:20 TEST

dwright at debian:/tmp$ ls -la test/TEST
