Mike!
That did it :-D
So setting the Variant to either:
my $nodes = Win32::OLE::Variant->new(VT_VARIANT|VT_BYREF);
or
my $nodes = Win32::OLE::Variant->new(VT_ARRAY|VT_VARIANT|VT_BYREF, 0);
and then use the foreach or for loop
foreach my $objItem (@{$nodes->Value()}) {
print 'Name: ' . $objItem->{Name} . "\n";
}
for (my $i = 0; $i != $objChildGroups; $i++) {
print 'Name: ' . $nodes->Get($i)->{Name} . "\n";
}
Returns the expected data.
I must admit that I don't quite get it at the moment, but hopefully some
more lines of Perl will help :-)
Could you point me to a book or online resources about Variants, Win32::OLE
for dummies?
Again thanks for your input - and thanks to Steven M as well.
Below is the final script, if someone needs it for future reference.

"WMI connection failed.\n";

exit 0;
}
my $objOV_NodeGroup = $objWMIService->Get("OV_NodeGroup");
