Ah wait, this is my fault. The prefs_init hook is used to provide the  
*default* value of the preference, not the *possible* values. The  
default value is of course still a string, and that's what the prefs  
hook should return. If you want to set a default value at all.

I don't think it's possible at the moment to set the available values,  
i.e. the value for the 'enum' entry, through a hook. So you may have  
to return back to set the 'enum' to the $db_results value in the  
prefs.local.php file.

Only if you want to set the provide the default value, i.e. the  
default from address, too, you need to use the hook.
