the script offers only YYYY-MM-DD and DD.MM.YYYY as easy option.
But you can use the TEXT OPTION: FREE WEB SOURCES SCRIPT CODE... fields for that.
Set DISCOGS_DATE to "no" and add the following code to
TEXT OPTION: FREE WEB SOURCES SCRIPT CODE FOR DJ SETS IN ONE FILE TRACKLIST SCRIPT
TEXT OPTION: FREE WEB SOURCES SCRIPT CODE FOR MULTISONG-TRACKS TRACKLIST SCRIPT
TEXT OPTION: FREE WEB SOURCES SCRIPT CODE FOR STANDARD SCRIPTS

This gives you MMDD as date, with 00 for missing day or month.
Discogs Master Release pages don't offer a release date, the have only year.
So you can only add
outputto "date"
say "0000"
to TEXT OPTION: FREE WEB SOURCES SCRIPT CODE FOR MASTER SCRIPTS if you want that.
