Use it as the first action (preferably in a macro group that is active only when the app is running, otherwise the AppleScript will fail obviously), and then the rest of your actions will follow it.
I tried to figure out what the "play" symbol was...but mine doesn't show that in the menu for some reason. Otherwise I would have included clicking that in the AppleScript as well.
ANOTHER option would be to set a global shortcut which it appears Tomato 2 can do from it's preferences pane. If you do this, you can have Keyboard Maestro simulate that keystroke which also opens the menu bar. See the screenshot as well as attached macro for that as well.
