No such code exists (patches are likely welcome), but the
real problem (and solution) is more complex, since MythTV
(and I believe WMC) does not sufficient retry logic to
pick and try another tuner *at* the time of the (failed)
recording, and scheduling (to retry at some future point)
becomes an interesting exercise (since will a tuner be
available at some future time?).

Bottom line, MythTV presume exclusive access to its tuners
for its own use (which was a perfectly reasonably design point
before tuners were network shareable).    The only recommended
solution for MythTV (or, for that matter WMC) is to have enough
tuners (and do not try to share them) to meet your peak
concurrent recording needs.
