Something like this should work (assuming the files don't already  
exist in the destination folder):

message = app('Mail').selection()[0]
for attachment in message.mail_attachments():
	attachment.save(in_=mactypes.File(u'/path/to/outfolder/' +  
attachment.name()))

Dunno offhand; might have time to look into it tomorrow unless anyone  
else has any ideas. As you say, Mail's scripting interface is less  
than stellar. BTW, you could also try asking on Apple's AppleScript- 
users mailing list; I expect there's a few folk there who've had  
dealings with Mail as well and might be able to shed some light on the  
problem.
