Thanks everyone, I adapted the script according to your suggestions.
Here is my version, which seems to work so far. Note that I reset jack
transport to 0 after stopping it. If you have any suggestions as to how
to improve it, please mention them. I am by no means an expert in bash
scripting. In fact, I pasionately hate that language.

#!/usr/bin/env bash

function jack_transport_status() {
  jack_showtime | head -n1 & >/dev/null 2>&1
  wait
}

if jack_transport_status | grep -q -i stopped
then
  echo play | jack_transport >/dev/null 2>&1
else
	echo stop | jack_transport >/dev/null 2>&1
	echo locate 0 | jack_transport >/dev/null 2>&1
fi
