Hi Pierre,

internally the markup-list-command `score-lines' transforms the given
score into a list of stencils.
The markup-command `score' calls `score-lines' and via
`stack-stencils' said list of stencils is spaced vertically.

The list of stencils itself contains no spacing-information. Spacing
in the markup-command `score' depends on `baseline-skip.
As for every multiline markup, like \column, flexible vertical spacing
\paper variables are ignored.

To mimic system-system-spacing.basic-distance = 15 you could do

\markup {
  \override #'(baseline-skip . 9.5)
  \score {
    \new Staff { \repeat unfold 10  { c' d' e' f' } g' \bar "|." }
    \layout {
      system-count = 3
      line-width = 90
      \context { \Score \override BarNumber.font-size = #-4 }
      \context { \Staff \magnifyStaff #5/8 }
    }
  }
}

Alas, system-system-spacing is a _flexible_ setting, baseline-skip not.

Cheers,
  Harm
