Marking all duplicates in each group, except those with the lowest number

[StefanDE]

Let's say I have duplicate groups like this:

Group 1
Picture_01.jpg
Picture_55.jpg

Group 2
Picture_4.jpg
Picture_13.jpg

Group 3
Picture_23
Picture_35.jpg
Picture_47.jpg

How do I use the Selection Assistant, so that I e.g. mark those pictures in a group with the highest number(s)? The ones, I printed in red here?

Please note:
Selecting "Filename > Highest/non-blank" won't work correctly.
This function considers e.g. "Picture_4.jpg" higher than "Picture_13.jpg"
Obviously "higher" is defined by ascending alphabetical order.

Any help would be appreciated very much.
