Title: Fix zero-ordering SORT when called against lists

People mostly use SORT against lists, but our prior
behavior was pretending lists were an unordered bag
requiring a forced-sort when no sort was requested.

We can just use the native list ordering to ensure
consistency across replicaion and scripting calls.

Tests added too (they fail before this commit).

Closes #2079
Closes #545 (again)
