That's a development snapshot.  The tested releases have numbers 
like "0.34".

You are seeing incomplete and buggy named-node support.  That 
version, by mistake, has named-nodes on by default, but they 
don't really work.

Reordering the nodes is correct behavior, but it is incorrect to 
show the reordered numbers to you.  Sometimes you see the user 
names.  Sometimes you see the internal numbers.

For sensible behavior, turn named nodes off:
".option nonamednodes"

There is a new development snapshot available 
It has named nodes off by default.  Named node support is still 
incomplete, but I am working on it.
