I am able to do this using xpath. If XML schema changes in a future release then this solution likely will not work. It works as of ElectricCommander 4.1.x.

I used findObjects API on "logEntry". This returns items that are shown in "View Log" link on the Workflow Details page.

I notice an inaccuracy in this approach when the transition taken was an "On Enter" transition. In this case, the previous state returned is the previous state that exited with "On Complete" transition.

 use strict;
 use ElectricCommander;
 $| = 1;
 my $workflowName = '$[/myWorkflow/workflowName]';
 my $projectName = '$[/myWorkflow/projectName]';
 my $ec = new ElectricCommander();
 my $xPath = $ec->findObjects("logEntry", {
     filter => {    propertyName => "containerName" ,
                 operator => "equals" ,
                 operand1 => "$workflowName" }
 #my $string = $xPath->findnodes_as_string("/");
 #print "$string \n";
 my $activeState = $ec->getWorkflow ($projectName, $workflowName)->findnodes("//activeState")->string_value();
 print "Active state: $activeState \n";
 my $totalCount = $xPath->findnodes_as_string("count(//logEntry/subject[contains(., 'state')])");
 #print "Total count: $totalCount \n";
 my $previousState;
 my $previousStateCount = $totalCount;
 do {
     $previousState = $xPath->findnodes("(//logEntry[contains(subject, 'state')]/subjectName)[$previousStateCount]")->string_value();
 } while ($previousState eq $activeState);
 print "Previous state: $previousState \n";

Update: This works on EC4.0 as well.
