$wfs is a reference to an array

I doubt that. What does the TeamSite documentation say?

Most likely, ->GetActiveWorkflows() returns an OLE collection, which would mean you have to work with $wfs->Count and $wfs->Item() or the in function of Win32::OLE.

If $wfs really contains a number after your assignment, then what you proposed should work. What happened when you tried it?
