With no
  \midi { \tempo 4 = 120 }
at the end of the score, the default is to generate a PDF.
If you add only a \midi, like here, then you only generate MIDI.
So what you need is:
  \midi { \tempo 4 = 120 }
  \layout { }
which will generate both MIDI and PDF.

The \layout { } in this position will use all the global layouts
that have accumulated (those layouts not inside \score blocks).

You can also add local layout options for just the one \score by adding
them here:

  \midi { \tempo 4 = 120 }
  \layout { … local layout options for just this score … }

Cheers,
David.
