Rick, I would wire C314 according to the schematic as a filament bypass. I would suspect the schematic is correct.
Sometimes the cathode of FM IF amp tubes is purposely left unbypassed to increase stability and control grid input impedance. The parts list refers to C314 as only an RF bypass, not a cathode bypass as some other caps in the list are referred to.
