Can parity violation bias the homochirality of biological molecules?

Predicted $\Delta E_{\mathrm{PV}}$ for amino acids and sugars corresponds to an equilibrium enantiomeric excess of order $10^{-17}$ at $300\,\mathrm{K}$ (estimate). Question: does any autocatalytic amplification mechanism (Frank-type autocatalysis with mutual inhibition, Kondepudi-Nelson bifurcation, Viedma ripening) under prebiotic conditions convert a bias of this size into a probability of selecting the natural handedness measurably different from $1/2$, given statistical fluctuations of order $N^{-1/2}$ in $N$ molecules and competing chiral biases (circularly polarized light, magnetochiral effects). An answer is a model with measured rate constants and volumes giving that probability, or an experiment showing PV-directed selection.
