You need to add the name after the application parameter of your URL (here I use 'itunes-u'):
https://itunes.apple.com/us/app/itunes-u/id\(appID)?ls=1&mt=8&action=write-review
Also note that the circuit works correctly, so you can call instead:
itms-apps://itunes.apple.com/us/app/itunes-u/id\(appID)?ls=1&mt=8&action=write-review
