We search for direct CP violation in charmless hadronic B decays observed in a sample of about 22.7 million BB pairs collected with the BABAR detector at the SLAC PEP-II asymmetric-energy e+e^\ensuremath- collider. We measure the following charge asymmetries: ACP(B^\ifmmode±\else\textpm\fi\ensuremath→\ensuremathη^\ensuremath'K^\ifmmode±\else\textpm\fi)=\ensuremath-0.11\ifmmode±\else\textpm\fi0.11\ifmmode±\else\textpm\fi0.02, ACP(B^\ifmmode±\else\textpm\fi\ensuremath→\ensuremathω\ensuremathπ^\ifmmode±\else\textpm\fi)=\ensuremath-0.01_ \ensuremath- 0.31 + 0.29\ifmmode±\else\textpm\fi0.03, ACP(B^\ifmmode±\else\textpm\fi\ensuremath→\ensuremathφK^\ifmmode±\else\textpm\fi)=\ensuremath-0.05\ifmmode±\else\textpm\fi0.20\ifmmode±\else\textpm\fi0.03, ACP(B^\ifmmode±\else\textpm\fi\ensuremath→\ensuremathφK^*\ifmmode±\else\textpm\fi)=\ensuremath-0.43_ \ensuremath- 0.30 + 0.36\ifmmode±\else\textpm\fi0.06, and ACP(B0\ensuremath→\ensuremathφK*0)=0.00\ifmmode±\else\textpm\fi0.27\ifmmode±\else\textpm\fi0.03.
