Well, if you can write a custom function that does the right thing with multiValued fields you could sort by that.
You still haven't defined the exact use case. The problem here is that sorting by a multiValued field is meaningless. Consider a field with aardvark and zebra. Where should it sort? Of course you can define rules like "the minimum value of the field", which will at least give consistent results... until the next person wants to sort by the average of all the numbers in a field.
