How to tile in left-right-bottom-top order in imagemagick montage

I have a several sets of numbered png images (mostly 00-23 but some are different lengths) that I am trying to combine in imagemagic开发者_开发百科k montage, but I need to have them tiled in left-right-bottom-top instead of left-right-top-bottom order. How can I do this?

You could use the "-scene" command to specify the "tile number". Check out the imagemagick documentation here.
