Returns array of resources in current map, ordered based on either CODE,
if this is a CODEd exam, or based on student's identity if this is a
"NAMEd" exam.

Should be used when randomorder and/or randompick applied when the
corresponding exam was printed, prior to students completing bubblesheets
for the version of the exam the student received.
