In general, you can't use objects as keys to a hash.

Given your current usage pattern, I would suggest reversing everything and, instead of $references->{$objref} = "value", try: 

  $references->{$objref->{_team}}{$objref->{_name}} = $objref;

That's assuming that no two objects can have the same name. If that's not the case, perhaps you really want arrays: 
  push @{$references->{$objref->{_team}}}, $objref;

Both examples here split everything up by team so that you can just skip over an entire hash or array rather than skipping over individual team members.

(This is in addition to japhy's advice to use the same variable name to refer to the same object ;-})
