[Maxima] simple simplification fails?

factor simplifies it most of the way. Unfortunately, factorsum doesn't
handle rz*z+ry*y+rx*x+r*rz^2+r*ry^2+r*rx^2 =>
rz*z+ry*y+rx*x+r*(rz^2+ry^2+rx^2) because rx, ry, rz appear in both
the r*xxx term and the rest.
You could also try playing with ratfac and ratvars variable ordering.

No, this is not the way it works. There is a standard simplification
algorithm which does no combinatorial search.
