Wrong sorting of run configurations

1. Open a project.
2. In Projects mode, open the run settings for the project.
   It has a run configuration with the same name as the project.
3. Create nine more run configurations for this project.
   They will get the indexes 2 to 10.
4. Check the contents of the combo box containing the different run configurations.
   They are sorted in alphabetic order, so the indexes are not in the correct order:
   

These indexed run configurations should be displayed in the correct numeric order.
