They both look OK to me.

Type modifiers applied to function arguments and results are generally
ignored. What you have here is functions returning numeric[], and not
anything else. In the plpgsql example the coercion to numeric(7,2)
happens because you stored into a local variable declared that way,
but there's nothing to make it happen in the plperl example.
