We find that although these two decays are both tree-dominated, the ratio of their penguin to tree contributions are very different: there is only a few percent for the decay $\\bar B_s^0\\to K^{*+}_0(1430)\\pi^-$, while about 37% in scenario I, even 51% in scenario II for the decay $\\bar B_s^0\\to K^{*0}_0(1430)\\pi^0$.
