Yeah, a snap cutter won't really work on such a narrow trim. If you don't
have too many, then I recommend an abrasive tile saw "blade" that fits in a
hacksaw frame. It's not a blade so much as an abrasive impregnated rod. I
had very good luck cutting commercial grade tiles with one of this back when
I did my bathroom. Looks like this:

You could also use a carbide grit-edged regular hacksaw blade.
Hope this helps.
I had a situation like that at my old house. I had installed ceramic
wall tiles and decided later to put some wood trim around the border but
wanted the trim to align with the counter top. I had to trim about a
quarter inch off the tiles. I got a Dewalt DW660 cut-out tool with a
ceramic bit. Sucker is strong. You need to hot-melt glue a straight edge
to the ceramic if you want a clean straight cut. I free-handed my cut
because I was putting trim around the tile.
If the tiles are not yet installed you might try hot-melt gluing the
tiles to a piece of plywood, laying a straight edge and trimming them
that way with the cut-out tool.
I've had fairly good results scoring the tile then gently clamping the smaller
part ( 1/4 inch in your case ) in my bench vise and giving the larger part a
sharp blow with my palm. Often it breaks cleanly all the way across, but
occasionally needs to be repositioned in the vise and given a clean-up whack to
break off any pieces that missed the first attempt. If there are still some
jagged edges remaining they get a few passes across my bench grinder.
Good luck Clint
