iTunesTrack location is nil in sandbox mode?

Question

I am sandboxing an osx app that uses scripting bridge to access iTunes.

        for(iTunesFileTrack* track in fileTracks)
        { 


           //url is nill in sandbox mode but good value in non sandbox mode
            NSURL* url = [track location];

            NSString* sourceFile = [[track location] path];

            if(sourceFile == nil)
            {
                NSLog(@"Sourcefile for the track %@ was nil", track);
                continue;
            }
         }

nil is returned, I am using following entitlements

            <?xml version="1.0" encoding="UTF-8"?>
            <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

                        <string>com.apple.iTunes.library.read-write</string>
                        <string>com.apple.iTunes.playback</string>
                        <string>com.apple.iTunes.podcast</string>
                        <string>com.apple.iTunes.user-interface</string>

                </dict>
                <key>com.apple.security.temporary-exception.apple-events:before:10.8</key>

                    <string>com.apple.itunes</string>
                </array>
            </dict>
            </plist>

The console shows following violation

  iTunes[1592]: AppleEvents/sandbox: Returning errAEPrivilegeError/-10004 and denying dispatch of event core/getd from process 'TestiTunesAccess'/0x0-0x4d04d, pid=1789, because it is not entitled to send an AppleEvent to this process.

it works fine in 10.7 and location is returned OK, but in 10.8 and 10.9 because the scripting-target entitlement is active, I can iterate the library but location of track is nil, why is that so ? if I just use temporary exception and remove the part:before10.8 then it works.

But since apple recommends we use scripting target in 10.8+ and not temporary exception entitlements, I am using the recommended ones. any help would be highly appreciated.

I fixed this by adding a temporary exception for iTunes, as shown in this answer.

<key>com.apple.security.temporary-exception.apple-events</key>
<array>
  <string>com.apple.iTunes</string>
</array>
