How do I move a \markup down?

[Arjan Bos]

In the following snippet, the \markup is to far from the system.

%% -- snip
\version "2.10.20"

%% uncommenting the next line will result in an error.
%%\override TextScript #'staff-padding = #0.1
\markup{\small 5. Variation (freier Anschlag)}
\score { d''4 }

%% -- snip

However, if I want to override either the padding or the staff- 
padding, lilypond tells me that the \override is unexpected. So how  
do I move down the markup?
