Using sh <script> will force using Bourne shell unless overridden by line #1
Both methods you suggest render #!/usr/bin/ksh ineffectual.

pfsh

pfexec(1)							   User Commands							 pfexec(1)

NAME

       pfexec, pfsh, pfcsh, pfksh - execute a command in a profile

SYNOPSIS

       /usr/bin/pfexec command

       /usr/bin/pfexec -P privspec command [ arg ]...

       /usr/bin/pfsh [ options ] [ argument ]...

       /usr/bin/pfcsh [ options ] [ argument ]...

       /usr/bin/pfksh [ options ] [ argument ]...

DESCRIPTION

       The  pfexec  program  is  used to execute commands with the attributes specified by the user's profiles in the exec_attr(4) database. It is
       invoked by the profile shells, pfsh, pfcsh, and pfksh which are linked to the Bourne shell, C shell, and Korn shell, respectively.

       Profiles are searched in the order specified in the user's entry in the user_attr(4) database. If the same command appears in more than one
       profile, the profile shell uses the first matching entry.

       The  second form, pfexec -P privspec, allows a user to obtain the additional privileges awarded to the user's profiles in prof_attr(4). The
       privileges specification on the commands line is parsed using priv_str_to_set(3C). The resulting privileges are intersected with the  union
       of  the	privileges specified using the "privs" keyword in prof_attr(4) for all the user's profiles and added to the inheritable set before
       executing the command.

USAGE

       pfexec is used to execute commands with predefined process attributes,  such as specific user or group IDs.

       Refer to the sh(1), csh(1), and ksh(1) man pages for complete usage descriptions of the profile shells.

EXAMPLES

       Example 1 Obtaining additional user privileges

	 example% pfexec -P all chown user file

       This command runs chown user file with all privileges assigned to the current user, not necessarily all privileges.

EXIT STATUS

       The following exit values are returned:

       0     Successful completion.

       1     An error occurred.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
