Weight option doesn't work with default drupal messages.

I'm having the same issue, but it's not just for the default messages. The weight setting for rules appears to be completely meaningless as far as I can tell. I was setting weights to create a certain execution order, but it always executes my rules in the order that they were first entered.

Ignore my last comment. What I thought was an issue caused by weights being ignored was due to something else. I still don't know that weights are working as expected, but I don't know that they aren't.

So the only question remaining is that of the original poster, @LTech.

Frankly I'm a little puzzled as to what this means:

I've given the message a weight of +10 but it still shows before the drupal default message.

First of all, the Drupal default message is not generated by Rules, so I'm not sure why you think that a Rules setting will control the default message (or any other non-Rules message, for that matter). Second, the Rules action "Show a message on the site" does not have a weight parameter. Messages created by Rules actions will show in the order that those actions were executed. If you're referring to the weight of the Rule itself, the description of that parameter says "Order rules that react on the same event. Rules with a higher weight are evaluated after rules with less weight." This gives no guarantee of order for rules which act on different events, or the order of Rules messages vs messages created by other modules - to do that you will have to hook into core Drupal. See #1839106: How to display a custom rules message *below* a system message? for ways to do that.
