??? When I try it here, I get a separate output PDF file for each
\book{...}. Bug or feature?
How can I use it to get all the resulting scores in the same file as
you describe it?

I have only partial success here. When trying the example attached at
the end of this email, I only get the first score line of the first
page, the second one is lost. On the second page, I get the desired
two score lines. Please debug and fix before version 2.6!

With the default treatment in lilypond-book, where each score line
is typeset in its own .eps file, it would be extremely tricky to
implement a \lpbookPageBreak, since then lilypond would have to
report information back to lilypond-book on where it should insert
the page break.
However, if you use the completely undocumented feature that you only
get one .eps file per page if you enclose your \score in a \book,
then you could use normal \pageBreak, as soon as the bugs have been
fixed.

Example:
\documentclass[a4paper]{article}

\usepackage{graphicx}
\begin{document}

Hello!

\begin{lilypond}
  \book {
    \markup {
        \fill-line { "High up above" }
    }
    \score {
        <<
            \relative {
                \clef bass
                d,2 d c4 bes a2 \break
                c2 c d4 f g2 \pageBreak
                d2 d c4 bes a2 \break
                c2 c d4 f g2
            }
            \addlyrics {
                My first Li -- ly song,
                Not much can go wrong!
                Next page will be here
                or may -- be else -- where
            }
        >>
    }
    \markup {
        %%TODO: make \verse markup.
        \fill-line {
            \line {
                "2. "
                \column {
                    \line { My next Li-ly verse }
                    \line { Now it's getting worse! }
                }
            }
        }
    }
    \markup {
        \fill-line {
            \line {
                "3. "
                \column {
                    \line { My last Li-ly text }
                    \line { See what will be next! }
                }
            }
        }
    }
}
\end{lilypond}
