Title: Allow ordering by field symbol (regression)

Fixes regression introduced by fix for Issue #75 in commit
c4a53de89c6d1886aa7960afd34e715dda080393. It wasn't documented or tested,
but previously we supported using a field symbol for the "order" option of
search_for. This commit adds that capability back (and a test).
