yes you did.

Look at the output you posted before and after the time you tried my suggestion. Your largest divisor is 1083 and most divisors are just 1, 2, or 3. But when you tried my sort suggestion you suddenly have stuff like:
9.742084/395690
All a sort can do is re-arrange the order in which the lines are printed. The smallest divisor you used which my suggestion is much larger than the largest divisor you used before and after. Well, that your prerogative I guess... use any data you want. But you didn't answer my question. Regardless of the data, when you used my suggestion, the output you got was sorted correctly by field three. Why do you claim otherwise?

asciitopgm

asciitopgm(1)                                                 General Commands Manual                                                asciitopgm(1)

NAME

       asciitopgm - convert ASCII graphics into a portable graymap

SYNOPSIS

       asciitopgm [-d divisor] height width [asciifile]

DESCRIPTION

       Reads ASCII data as input.  Produces a portable graymap with pixel values which are an approximation of the "brightness" of the ASCII char-
       acters, assuming black-on-white printing.  In other words, a capital M is very dark, a period is ver light, and a space  is  white.   Input
       lines which are fewer than width characters are automatically padded with spaces.

       The  divisor  argument  is  a  floating-point number by which the output pixels are divided; the default value is 1.0.  This can be used to
       adjust the brightness of the graymap: for example, if the image is too dim, reduce the divisor.

       In keeping with (I believe) Fortran line-printer conventions, input lines beginning with a + (plus) character are assumed  to  "overstrike"
       the previous line, allowing a larger range of gray values.

       This tool contradicts the message in the pbmtoascii manual: "Note that there is no asciitopbm tool - this transformation is one-way."

BUGS

       The table of ASCII-to-grey values is subject to interpretation, and, of course, depends on the typeface intended for the input.
