The token %state_name in the drupal_set_message after scheduling a node for a state change has no output. Probably the watchdog message too. Currently lines 591 & 592 of workflow.inc.
It looks like the problem is the string $state_name is being passed to function workflow_get_state_label($sid), which is looking for a numeric sid?

johnvITMT, this is fixed in 7.x-2.x . D6-versions are not maintained anymore.
Your version 6.x-2.x is used very rarely. Better use 6.x-1.2.
