"Score" like in \new Score { ... } is one of many available contexts
like StaffGroup, Lyrics, Voice etc
"score" like in \score { .. } is _not_ a context.
>From Learning Manual:
  Every \score block is a separate chunk of music within a \book block.
  A \score block must always contain exactly one music expression.
  the \score block can contain other things, such as
  \score {
    { c'4 a b c' }
    \header { }
    \layout { }
    \midi { }
  }

To summarize, you can't write a \header inside a context and you can't
have two musical expression inside \score { ... }
NB \set whatever _is_ a musical expression.

You could do
\score {
  {
    \set Score.skipBars = ##t
    \relative c' {
    \repeat unfold 2 {f4 e d c} R1*10 \repeat unfold 2 {f4 e d c}
    }
  }
  \header { piece = "II."}
}

But if you want skipBars = ##t in a single score put it in a score-layout:
\score {
  \relative c' {
  \repeat unfold 2 {f4 e d c} R1*10 \repeat unfold 2 {f4 e d c}
  }
  \layout {
    \context {
      \Score
      skipBars = ##t
    }
  }
  \header { piece = "II."}
}

If you want it for all scores use layout outside from \score
\layout {
  \context {
    \Score
    skipBars = ##t
  }
}

\score {
  \relative c' {
  \repeat unfold 2 {f4 e d c} R1*10 \repeat unfold 2 {f4 e d c}
  }
  \header { piece = "II."}
}

Btw, I think the Learning Manual covers all this.
The usage of \new Score is possible, yes, but I've never found a
use-case for it, apart from testing very strange things ;)
