Scores within a book in two columns

[Sven Axelsson]

Is there a way to typeset a number of one line scores within a book in
two columns?

Ideally I'd like something like

\book {
  \score {}
  \markup {
    \column {
      \score {}
      \score {}
    }
    \column {
      \score {}
      \score {}
    }
  }
}

but that doesn't work, at least not with 2.14. I really like to use
score so I can get headers and stuff for the fragments, but if there
is another, more manual way, that can work too.

Thanks
