So apparently you cannot use $CEX, $CEY, CEZ anymore?

I get a
syntax error, invalid syntax
!

But how would you use centroid() on the Pivot parameters of a Transform SOP inside a For Each block?

If I try

centroid(opinputpath("."),0)
I also get an error,

Unable to Evaluate expression. Name ‘centroid’ is not defined

I can use $CEX, $CEY, $CEZ with no problems.

You have some typos in your centroid expression, this works for me:
centroid( opinputpath( ".", 0 ), D_X )
centroid( opinputpath( ".", 0 ), D_Y )
centroid( opinputpath( ".", 0 ), D_Z )
