Here is mine, too.  It's web-based (so the files load a bit slow  
unless you are on the same network as the file!).  To run it, put all  
three attached files in a folder, then put all of your audio files in  
the folder.  One file MUST be reference.something (eg reference.wav)  
or it won't work.  The script uses that as the reference and  
randomizes the rest.  No other setup is needed - just make sure all  
files are in the same folder.  Also make sure that one of your coded  
files is a 3.5 khz low-passed reference, to comply with the MUSHRA  
requirements.  When the user submits, the results are just dumped out  
- it could send via email or to a mysql database or something, but  
that would require more setup.  Here is a demo:
