Comment(by malb):
Okay, I understood: the variables in the polynomial instead of in the
ring. If we take the variables of the ring, everything is fine.
Note, however, that this implies that your original example will fail (?)
{{{
#!python
sage: R.<y_6, y_3, y_2, y_1, z_6, z_5, z_4, z_3, z_2, z_1> = GF(3)[]
sage: S = GF(3)['y_4', 'y_3', 'y_2', 'y_1', 'z_5', 'z_4', 'z_3', 'z_2',
'z_1']
sage: S(y_1*z_2^2*z_1)
}}}
