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

       pyntor-selfrun - creation of self-extracting presentation archives

SYNOPSIS

       pyntor-selfrun [OPTIONS] presentation-archive|presentation-directory

DESCRIPTION

       Pyntor  is a presentation tool which can display slides and effects of various formats.	The tool pyntor-selfrun allows one to create self-
       extracting archives containing both the presentation and Pyntor itself, so that it can be run on  computers  where  Pyntor  itself  is  not
       installed.  It also ensures independence of the corresponding Pyntor version, as future changes of the application do not affect the previ-
       ously created presentations.  The way pyntor-selfrun works is that it takes the presentation-archive  in  question,  packed  as	a  tarball
       (which  might be named *.pyntor), and the release tarball of Pyntor which must be present somewhere. Using a template file, it then creates
       the self-running and self-extracting script for distribution.

       In case the presentation-archive does not exist yet, pyntor-selfrun can create it automatically from a presentation-directory. This is use-
       ful even when not creating self-extracting archives, see the -a option.

OPTIONS

       -t, --template=templatefile
	      Uses  a  template  different  from  that one which is shipped with Pyntor and used by default. The template is a script in Python or
	      another scripting language, which contains the variables %PYNTOR% and %ARCHIVE% which are replaced with the base64-encoded  contents
	      of the two files given as arguments to pyntor-selfrun.  This option is not recommended for most cases.

       -a, --archive
	      Creates a pyntor presentation-archive from a directory which contains a script file, local data files and optionally some local com-
	      ponents.	This is a convenience operation, since presentation archives are just tarballs, but in the future  some  checks  might	be
	      done here.

       -r, --release=sourcetarball
	      Specifies  where	to find Pyntor itself to include it into the self-extracting archive. The source tarball should be a released pyn-
	      tor-*.tar.gz file.

       -h, --help
	      Displays a summary of all available command line options.

BUGS

       In a future version, pyntor-selfrun should allow to create *.pyntor archives automatically by examining a script file, including only those
       files of Pyntor which it really needs.
