Only when there is no ATSC major an minor or when 'quick tuning' is
enabled. The 'serviceid' is a less reliable than the ATSC tuning info.

This is the norm in the USA.

I would prefer in order:
 * improve lt_smart to allow '12_1', '12.1', etc. to be treated as a
   floating point number.
 * add a new sorting method in addition to lt_smart and lt_callsign
 * add a sort value to the schema.

I think either of the first two options would work for example.
