First answer "what does sorting on a field with more than one value
mean?" Say I have
"aardvark" and "zebra". Where should the doc go, at the beginning or
end of the list?

For numerics at least you can do this, see:
https://lucidworks.com/blog/2015/09/10/minmax-on-multivalued-field/
in Solr 5.3+.

If it's a fixed sort kind of thing an alternative is to extract the
value at index
time that you want to sort by (once you've defined what sorting on this
field means) and put that in a separate, single-valued field.

Best,
Erick
