Leading Zeroes in Bin Tile Display

This is really wierd. 

I've exported a speaker's slides as PNGs, which are named Slide 1, 2, 3...10, 11, 12, etc., without leading zeroes.  I forgot to put them in.

I dropped them in a bin which came up in list view. Everything sorted nicely, running 1, 2, 3 as expected.

But when i shifted to tile view, they were listed, 1, 10, 100, 2, 20, 3, etc.

I discovered in tile view I can choose "List View sort" in the sorting  area, and it straightens out.  But if it's in User Order, it's all messed up. And if I put it in Freeform View it can't be sorted except by manually moving things around.

Why is this???  Why can't User Order and Freeform View default to the 1-2-3 order?

BTW this also happens if I'm importing a bitmap stream as a clip and forget the leading zeroes. I've resorted to running stills through Lightroom and exporting with a letter followed by leading zeroes.
