Hi
import maya.cmds as cmds
myDimNode=cmds.createNode("nearestPointOnMesh")
cmds.connectAttr('pPlane1.outMesh',myDimNode+'.inMesh')
myReult=cmds.getAttr(myDimNode+".nearestFaceIndex")
print myReult
i can get the result like this i am using maya 2009 ..closestPointOnMesh
changed to nearestPointOnMesh
check it
