A little adhesive will keep the guide in place when you're changing cables.
And FWIW, cables rubbing directly on the BBshell isn't a huge problem, either. Many manufacturers used to do this, either by filing a channel for the cable, brazing loops or tunnels onto the shell to guide the cable, or having channels cast into the shell itself as part of the shell design.
