Ok, in emacs bzr I added a new defcustom:

,----[ C-h v reftex-label-ignored-macros-and-environments RET ]
| reftex-label-ignored-macros-and-environments's value is nil
| 
| Documentation:
| List of macros and environments to be ignored when searching for labels.
| The purpose is to ignore environments and macros that use keyval
| style label=foo arguments, but the label has a different meaning
| than \label{foo}.  For example, TikZ defines several
| environments and macros where [label=foo] defines the label to be
| printed at some node or edge, but it's not a label used for
| referencing.
| 
| Note that this feature is only supported if you are using AUCTeX
| and the functions `TeX-current-macro' and
| `LaTeX-current-environment' are bound.  Also note that this
| feature might slow down the reftex parsing process for large TeX
| files.
| 
| You can customize this variable.
`----

So add "node" and "shape" (and "axis" from the other example) to that
variable, and keyval style label=foo are ignored for these macros and
environments.

Bye,
