How do I set macport python to be default?

With your path variable set as above the MacPorts python should be found
first. Which makes me suspect that PATH gets modified after set to the
value above.
You should check the output of:

echo $PATH

If that differs from the above setting check your bash startup scripts
whether any of them modify the PATH after your setting takes place.
On my system MacPython modified .bash_profile by prepending it's
location onto the PATH thus overriding my own setting.
