Try with this. What modified? In case fifth field is an alphabetic character, asign the ninth column to value variable, else assign the eigth one. And work with that.
Code:
$ awk 'BEGIN { max = -1; min = -1 }
  $4 == "TB" {
    value = $5 ~ /^[[:alpha:]]$/ ? $9 : $8;  
    max = max < value ? value : max;
    min = (min == -1 || min > value) ? value : min
  }
  END { printf "max = %.3f\nmin = %.3f\n", max, min }
' infile
max = 87.730
min = 66.630

NAME

       lockward - Rotating spinning color-cycling things

SYNOPSIS

       lockward  [-display  displayspec]  [-root]  [-window]  [-visual	arg]  [-window-id  arg]  [-delay usec] [-pair] [-fps] [-blink | -no-blink]
       [-rotateidle-min msec] [-rotateidle-max msec] [-blinkidle-min msec] [-blinkidle-max msec] [-blinkdwell-min msec] [-blinkdwell-max msec]

DESCRIPTION

       lockward draws a spinning, rotating set of notched wheels overlaid with some flashing effects, using OpenGL.  It's a sort of cross  between
       the wards in a combination lock and those old information displays that animated via polarized light.

OPTIONS

       -visual visual
	       Specify which visual to use.  Legal values are the name of a visual class, or the ID number (decimal or hex) of a specific visual.

       -window Draw on a newly-created window (default).

       -root   Draw on the root window.

       -delay microseconds
	       Per-frame delay, in microseconds.  Default: 20000 (50 frames/sec).

       -blink | -no-blink
	       Enables/disables the blinking effects.  Default: Enabled.

       -fps    Display the current frame rate, CPU load, and polygon count.

       -rotateidle-min milliseconds

       -rotateidle-max milliseconds
	       The minimum and maximum time each spinner will sit idle, in milliseconds.  Defaults: Min 1000, max 6000.

       -blinkidle-min milliseconds

       -blinkidle-max milliseconds
	       The minimum and maximum time between blinking effects, in milliseconds.	Defaults: Min 1000, max 9000.

       -blinkdwell-min milliseconds

       -blinkdwell-max milliseconds
	       The minimum and maximum dwell time for the blinking effects, in milliseconds.  This affects how quickly the blinks actually happen.
	       Defaults: Min 100, max 600.

ENVIRONMENT

       DISPLAY Default host and display number.

       XENVIRONMENT
	       Name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
