Since the other two tab pages get added first (because the constructor and InitializeComponent of the parent form fire first) they appear first in the TabControl. To change the order, you can add code in the constructor of your form (after the call to InitializeComponent) that removes the two inherited pages and adds them back in again. For example:

this.TabControl.Controls.Remove(this.ListPage);
this.TabControl.Controls.Remove(this.PropertiesPage);
this.TabControl.Controls.Add(this.ListPage);
this.TabControl.Controls.Add(this.PropertiesPage);
