I would discourage this idea.  Then you wind up having a priority which
means something OTHER than a display priority.  I would prefer to keep
the priority ONLY for how often a standard screen will be shown.

Setting up a screen called "exit" is simplicity from both ends; then all
the server really has to do is extract "exit" from the screen_list, and
save a pointer to it in a global location:

screen* exit_screen, s;

// ....take a screen (exit) out of the list...
// ....contained in s...

exit_screen = s;
return 0;

This suggests a Dynamic Exit Screen, which makes it MUCH more
complicated... if you give such a message, then when do you stop taking
input?

Better idea would be to NOT remove exit from the screen list, but keep
it there and don't display it.  Then when the exit comes, just find the
exit screen in the list and use it.
