This is a very late response to this thread: Orlando Int'l Airport Emergency Tower Frequency
This is actually the "discrete emergency" frequency. More information on that can be found here: Aircraft Rescue and Fire Fighting Communications
As for what traffic you might hear on it, it would basically all be on the ground and it would be used in the event that an aircraft having a mishap would need to talk to ARFF/Operations personnel directly. At MCO, they will rarely use 133.37, but it has been done. Often if it is available, East Ground (126.4) will be used, Clearance Delivery (134.7) is another option. If it's not too busy, they might just talk on the tower frequency without changing. However, in the event that all ground based frequencies are in use, 133.37 provides an agreed upon frequency that may be used as a "private line" between the aircraft with a problem and supporting airport personnel.
I heard traffic on it within the last several months when a 737 blew a nosegear tire and Operations talked to the airplane while they arraigned for a tug to come out and tow the thing to the gate as they couldn't taxi because it was "too bumpy." Most towered airports I'd imagine have such a frequency available to them, but as they often have several frequencies they combine when traffic levels are low, it's just easy to use one of the combined frequencies that isn't in active use. If you're not close enough to the airport to hear ground transmissions, I wouldn't bother with it but if you live/spend time near the airport keep it in mind because it could be used at any time, though you'd most likely just hear:
"Is my fire flat?" "Yep, it's flat."
"How hot are my brakes?"
"Are we leaking anything?"
I did hear it get used as a tower frequency once and only once when someone was screwing around on one of the main frequencies, But once they went to one tower controller they used one of the published frequencies. Never heard that happen again.
