Always happy to help, Sam. This request is within the feature set of InDesign, so it should be doable. If you figure this out, please swing back and let us know what the answer is. I'm sure it will help somebody else down the road.

I'm getting nowhere with this—I'm sorry. I downloaded the trial version of the font and I can't make heads or tails out of it. I think the next step is to contact the font vendor—I suspect they can give you a hand.

Don't give up yet. The link you posted shows "The desktop version is delivered in OTF format." so if the alternates are there, you can access them the way I mentioned, above. 

Try this:

1. Type a number in a text frame.
2. Select it, and point to the blue bar underneath. Do at least two options appear?
3. If so, click the triangle to open the Glyphs panel:
   
4. Hover over the number style you want and tell us what it says on line three (above the name).

Set this up by nesting a character style in the list paragraph style.

If the font offers the second figure style that you are showing us—and I assume it does because you are showing us—create a character style to change the figure style. For example:

Then assign the character style to the List paragraph style.

Not all fonts offer old style and lining (and proportional and tabular) numbering, but for those that do you can set the choice in Paragraph styles.
