Commandblock specific player name and arguments broken

When I use a commandblock and write a code with a specific player name and arguments. I expect the commandblock to execute the command when redstone power is aplied.

Instead when redstonepower is provided nothing happens.

1. Place commandblock and type:tp taurus110 [x=100,y=65,z=2,r=3] 55 12 -399
2. Apply redstonepower to the commandblock
3. Notice nothing happens when in- or outside of the search radius at the specified coordinates.
