That should do what you want.  I still don't think it should be the 
default behaviour to automatically fall back to alternate versions.  As 
as rule, you shouldn't get a download you didn't ask for.  If you want 
some sort of automatic fallback, then implement an option setting to 
switch it on. That leaves it up to the user.  It would be fairly 
straightforward: if the new option is set, then populate the versions 
setting with "default,signed,audiodescribed", just as if you'd entered 
it on the command line, and let get_iplayer do its thing as normal. 
Whatever you do, don't break existing behaviour, as would happen with 
your earlier patch.  And there's also another wrinkle to consider: 
audiodescribed programmes are usually only available at a single 
recording quality, so you'd have to somehow square that with any user 
settings for --modes.
