interpolate Vim function arguments and shell commands

I've written a little .applescript file that can reload Safari. I've tried to hook it's execution into vim's BufWritePost event, (so Safari auto-reloads on file save).

I've placed this in my .vimrc:

function! SaveAndReloadSafari(delay) 
   " THIS IS WHERE MY PROBLEM IS>>>>>>>>>>>>>>> 
   !osascript ~/MySrc/applescript/reloadSafari.APPLESCRIPT a:delay
endfunction

if !exists("b:my_autocommands_loaded")
  let b:matts_autocommands_loaded = 1 

  au BufWritePost *.html,*\.css,*.js call SaveAndReloadSafari(0)
  au BufWritePost *.scss call SaveAndReloadSafari(2)
endif

As you can see, I want to add a 2 second delay after saving an .scss file (to allow my SCSS files to auto-compile to CSS)

I've confirmed that the only piece of the puzzle missing is my syntax for interpolating the a:delay with the shell command. (Executing the command without a delay parameter works fine).

What's wrong with my syntax?

You can use :exec

exec '!osascript ~/MySrc/applescript/reloadSafari.APPLESCRIPT ' . a:delay
