Are you sure you are in the jackuser group?
$ groups|grep jackuser

Oh, and you should set rtrprio much higher. 100 should
be enough. :-)
You should also add the line

@jackuser - nice -20

I also wonder which distibution you are using?
Normally, the realtime user is called "audio"...?
I don't know if it would make any problems though
but maybe.
