My supervisord.conf entry for a pool of working images was:

[program:psworker]
command=/home/trentosur/perfectstore/pharo-vm/pharo --nodisplay
/home/trentosur/perfectstore/ps.image worker.st 818%(process_num)1d
process_name=%(program_name)s_%(process_num)02d ; process_name expr
(default %(program_name)s)
numprocs=2
directory=/home/trentosur/perfectstore
autostart=false
autorestart=true
user=trentosur
stopasgroup=true
killasgroup=true


Part of the worker.st file handling the port number was:

"Seaside server start"
Smalltalk isHeadless ifTrue: [
  Smalltalk commandLine arguments
    ifEmpty: [
      Transcript show: 'No port parameter was specified.'; cr.
      Smalltalk quitPrimitive. ]
    ifNotEmpty: [:args |
      | port |
      port := args first asNumber asInteger.
      Transcript show: 'Starting worker image at port ', port asString; cr.
      ZnZincServerAdaptor  startOn: port.
      ZnZincServerAdaptor default server debugMode: false.
    ]
  ]
  ifFalse: [
      | port |
      port := 8080.
      Transcript show: 'Starting worker image at port ', port asString; cr.
      ZnZincServerAdaptor  startOn: port.
      ZnZincServerAdaptor default server debugMode: true.
    ].


I hope it helps.

Best regards,
