The order in which the directories are listed is important.  In the above, /opt/local/bin is ahead of all of the other directories, so that you will get the MacPorts versions of commands rather than the versions that are in other directories (the Apple provided versions are usually in /bin or /usr/bin).

The command you were using probably didn’t accomplish this for you because ${prefix} is a variable used to specify the MacPorts directory, which probably wasn’t defined.  I believe the MacPorts instructions use ${prefix} rather than /opt/local because it is technically possible to install MacPorts in a location other than /opt/local.

This preference setting should allow you to configure which shell is used by Terminal.app.  You many need to change the setting to ‘/opt/local/bin/zsh’ to use the MacPorts version of zsh.
