It's my understanding that Solr will refuse to sort on a multivalued 
field, returning an error.  If Solr were to make a decision to use the 
first value, or the minimum value, or the maximum value ... some users 
would think that was the wrong choice.

You can use a function query to have it sort on the min or max value of 
a field.
