When you specify a sort parameter it totally overrides the
scoring. You can specify multiple sort criteria, e.g. both
live_dt and score. If you specify two sort criteria, any
ties in the first are broken by the second and so on through
as many sort criteria as you have specified.

Note that specifying secondary etc. sort criteria if the first
one is unlikely to result in a tie is pretty useless. I.e.t if
sorting by millisecond dates there will (probably) be very
few ties.

Best,
Erick
