Using the formalism recently developed for the conventional Hall effect in granular metals, we calculate the residual anomalous Hall conductivity $\\sigma_{xy}$ and resistivity $\\rho_{xy}$ and weak localization corrections to them for both skew-scattering and side-jump mechanisms. We find that, unlike for homogeneously disordered metals, the scaling relation between $\\rho_{xy}$ and the longitudinal resistivity $\\rho_{xx}$ does not hold.
