try this:

<<<
\version "2.12.2"
{
\once \override Score.MetronomeMark #'outside-staff-priority = #1500
\tempo "Ziemlich langsam" 4 = 66
R1
\once \override Score.RehearsalMark #'outside-staff-priority = #1000
\mark \default
R1
}

>>>

the documentation trail for this is fairly convoluted:

NR 4.4.5 "Vertical collision avoidance"
http://lilypond.org/doc/v2.12/Documentation/user/lilypond/Vertical-collision-avoidance

find that there is a property outside-staff-priority and that objects  
are ordered with ascending priority away from the staff, then look up  
the two objects:

IR 3.1.62 "MetronomeMark"
http://lilypond.org/doc/v2.12/Documentation/user/lilypond-internals/MetronomeMark

IR 3.1.80 "RehearsalMark"
http://lilypond.org/doc/v2.12/Documentation/user/lilypond-internals/RehearsalMark

determine the values for RehearsalMark and MetronomeMark are #1500 and  
#1000 respectively, so swap them with the \override command.

the trick is knowing that you're looking for vertical-collision- 
avoidance rather than vertical placement of objects...
