We present measurements of the time-dependent CP-violation parameters
S and C in the decays omega K0S, eta'K0, reconstructed as eta'K0S and
eta'K0L, and pi0K0S.  The data sample corresponds to the full BABAR
dataset of 467 x 10^6 BB pairs produced at the PEP-II
asymmetric-energy e+e- collider at the Stanford Linear Accelerator
Center.  The results are
S_{omega K0S} =  0.55^{+0.26}_{-0.29} +/- 0.02,
C_{omega K0S} = -0.52^{+0.22}_{-0.20} +/- 0.03,
S_{eta' K^0}  =  0.57 +/- 0.08 +/- 0.02,
C_{eta' K^0}  = -0.08 +/- 0.06 +/- 0.02,
S_{pi0 K0S}   =  0.55 +/- 0.20 +/- 0.03, and
C_{pi0 K0S}   =  0.13 +/- 0.13 +/- 0.03,
where the first errors are statistical and the second systematic.
These results are consistent with our previous measurements and the
world average of sin2beta measured in B0 -> J/psi K0S.
