I figured out a bit of a workaround for what I had in mind: Add whatever metadata I want to sort by to the formatted song title, then enter a bunch of spaces, then enter the metadata that I originally wanted to display in the title. Add a bunch of spaces to the caption too so that it lines up under the title. Figured I'd share:

Only drawback is that the vertical alignment of title and caption changes relative to the length of the initial metadata, but that's workable. In this case, I'm using just numerals to indicate counts (whether a piece is "in 2," "in 3," etc.).
