set global priority order (lyric and dynamic)

[Cordelia]

Hello,

how can i change the global order of apparition ?
I need to have the lyric before the dynamics; I thought I could make it with 
priority but I cannot figure out where I’m wrong.

Exemple:

melody = \relative c' {
  \clef treble
  \key c \major
  \time 4/4

  a4 \mf \> b \p c-! \ff d
}

text = \lyricmode {
  Aaa Bee Cee Dee
}

\score{
  <<
    \new Voice = "one" {
      \autoBeamOff
      \melody
    }
    \new Lyrics \lyricsto "one" \text
  >>
  \layout {
    \Staff {
      \override DynamicLineSpanner.outside-staff-priority = #500 % Default #250
      \override TextSpanner.outside-staff-priority = #100 % Default #350
      \override TextScript.outside-staff-priority = #100 % Default #450
    } 
  }
  \midi { }
}


Thank you !
happy holidays
