Some texts list cystein as nonpolar, and others as polar...
What should I regard it as for the MCAT?

Cysteine: it's the only R group that has a higher priority than the CO2.
But it is still L; it has the same effect on the polarimeter.

cysteine is also a titratable group, the side chain has a pKa of ~8.
