The behavior was confusing from the user point of view - the "Default" meant
the handout layout (that by default is 6 slides per page), not any kind of
default.  And it looked like the orientation does not work.

Let's provide better wording instead of "Default" at least.

The ideal would be also to disable the "Order" when "According to layout" is
chosen.   Unfortunately it is not easily possible, as the enabling/disabling
is controlled by the UIControlOptions's mnDependsOnEntry, and that allows only
one value; and we'd need "everything but the 0" there.
