Signo and Coda

[Jean Bergeron]

Hi,

I'm trying to achieve to put the signo and the Coda at the right place but
it looks like I'm unable. I'm surely missing someting.

I want an 'al coda' on top of a Coda at the first bar "||"
then a Signo on the top of the second bar "||" (at the end of the line)

and start the other line with a CODA on top of the sign Coda before the
beginning of the staff.
It gave me everything but that.
Here is my code.
{
ees'' g'2 ees''4 d'' c''
\override Score.RehearsalMark #'break-visibility = #begin-of-line-invisible
  \once \override Score.RehearsalMark #'font-size = #1 #'self-alignment-X 
#RIGHT
  \mark \markup { "Al coda" \hspace # 1 \raise #-3 \musicglyph
#"scripts.coda" }
bes'2 aes'4 \bar "||"
\override Score.RehearsalMark #'break-visibility = #begin-of-line-invisible
  \once \override Score.RehearsalMark #'font-size = #1 #'self-alignment-X 
#RIGHT
    \mark \markup { \musicglyph #"scripts.signo" }
g'2 f'4 g' 2. ~ g'2 r4 \bar "||"    \break
\override Score.RehearsalMark #'break-visibility = #begin-of-line-invisible
  \once \override Score.RehearsalMark #'font-size = #1 #'self-alignment-X 
#RIGHT
    \mark \markup { \musicglyph #"scripts.coda" }
g'2 b'4 c''2. ~ c''2. ~ \bar "||."  c''2. ~c''2.   \break
r2. r2. r2. r2. r2. r2. \bar ".||" \break
     }
