Rhun's seems to be the logical answer as an analogy to weapons, but in thinking about this:
A sword gets +1 from MW because the sword is better made. A sword gets +2 from an enchantment because, again, the sword is better - in this case, magically. So, it makes some sense that these don't stack.
The tools get +2 from MW because the tools are made better. However, the +5 from the enchantment is actually improving the user's skill, not the quality of the tools. So, I can see an argument either way to be honest.
