ItemOptions, getOptionTop-methods, numbertype: 'my implementation plan'

Since i have a nice list of things i want to implement into the Nucleus core, i created an overview of it at my wiki and there you find a page for every feature, with the status of the development (implementing, proposed, done,...)
Currently i'm implementing the ItemOptions, well in fact that is ready, except the testcases.
While i was implementing these itemoptions i started to think about getOptionTop-methods. With these methods plugins will be able to retrieve an ordered array of the x highest or x lowest values of an option. Because this is used in some plugins that could be using itemOptions in the future, like NP_View, NP_Karma, etc, i started developing these methods as part of my itemoptions implementation. But when i thought i was ready i discovered that options with a 'numerical' value, like my testcase NP_Karma, don't sort right since they are sorted as text. That's why i started thinking (again) about a numerical type for options, which i need to implement now before i can finnish the getOptionTop methods.
I today decided that it is not good to wait with publishing the ItemOptions so i created a seperate wikipage to keep the development of the getOptionTop-methods. After these features I have the following items in mind:

• Optiontype: readonly and hidden
• event: PostNucleusUpgrade
• TemplateOptions
• SkinOptions
• CommentOptions (still thinking about this)
• 'Guided uninstall' (also still considering)
• Plugin upgrade functionality (this is a big one)
• Lists-of-Things (far far future)
