The app from play store that you suggested.
It is in /data/app with rw-r--r-- permissions so it should work.
I attached the apk just in case if you want to check some things.
The SystemUI.apk has this line in the AndroidManifest.xml:
<permission android:name="com.sonymobile.permission.TASK_SWITCHER_PLUGIN_VIEW" android:protectionLevel="signatureOrSystem" />
and this one is in the TaskKiller.apk's AndroidManifest.xml:
<uses-permission android:name="com.sonymobile.permission.TASK_SWITCHER_PLUGIN_VIEW" />
the TaskKiller is asking for permission from SystemUI instead of framework-res, idk why.
