If you're not kidding, I actually have an answer for you:

 mplayer `grep 112 playlist | cut -d" " -f2`

where your playlist file is numbered with a space between the number and 
the file names, and where there are no spaces in the file names.  Note 
those are back-ticks causing the entire expression they enclose to be 
executed before the result is passed to the mplayer executable.

I assume you understand those utilities but if not, grep 112 playlist 
looks for a match to that file you wanted to play, and cut -d" " -f2 
selects just the file name found in field 2 of the line cut at the space 
character.

Now, before you complain that that's a self-defeating amount of typing, 
just return to that command in your shell's history and simply change 
the number to play my preference, for example - track 111.

If you are kidding, you should be ashamed of yourself...  P - )
