This is a behavior changes (may be related to Change 2850) which is
not documented in Canvas.pod (in Tk-804.027).
Here's a patch for the doc:
diff -Naur Tk-804.027.old/pod/Canvas.pod Tk-804.027/pod/Canvas.pod

The items are returned in stacking order, with the lowest item first.

Thanks for the patch.
This wasn't a deliberate change, but a side effect of cleaning up
