Comptuer simulation on a two-dimensional anisotropic lattice-gas model of oxygen ordering in high-{ital T}{sub {ital c}} supeconductors of the YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} -type shows that the ordering dynamics obey algebraic growth laws which are different in the ortho-I and ortho-II phases. It is possible to relate this dynamical scaling behavior to a similar scaling in the experimentally observed temporal variation of the superconductivity transition temperature, hence suggesting a specific coupling between the coherence of oxygen order in the basal Cu-O planes and the superconducting state.
