Since Inventor ETO 2012 I'm not able to affect the order of my parameter rules in my Edit Parameter Window.
Before it was sorted alphanumerical by the DisplayName.
Who knows how to handle that?

Use Part Editor rule annotations.
See the Wikihelp
There are several ways to affect the order of parameters in the part editor. There is the sorting buttons on the part editor dialog (category view vs alpha-numeric sort). The alpha-numberic sort overrides any annotations that may applied for sorting. When in category sort order, you can use the rule annotation %%Category to set the categories of rules. Rules are sorted alpha-numerically within categories.
You have greater control with the Design Annotations %%CategoryOrder, %%OpenCategories, %%PartEditorRules, and %%PartEditorCategories.
Hope this helps.
