Using "Point Unreliable" status in Meta point

I'm trying to find out how to use the "Point Unreliable" status in Mango to select between bad sensors when one dies.
For example, I have (3) Sensors, all merrily logging data under Normal Conditions. Generally, we use an average of (2) of these sensors to do things with. Then, along comes a Badger who eats our comm cable (or whatever) and one of our sensors stops responding via Modbus.
Mango tells us that that that sensor's data point is now "point unreliable" and we raise an event to signal that someones' gotta fix it. However, in the meantime, we still need to run calcs with the other (2) good sensors. Basically, I need my meta point to automatically see that "this point is unreliable" and switch to the second (or third) sensor.
Basically, I'd like something similar to the getDataPointWrapper()'s "Enabled:True", but that instead returns "PointUnreliable:true" or something. It would make sense to me that such a thing would be available via getDataPointWrapper(), but it doesn't appear to be there.
Where does one find the "point unreliable" status via scripting / meta point? If possible, I'd like to avoid using the Events to detect this, as we have MANY cases of this kind of thing, some of which are already covered by other alarms /events / whatever.
