Sorting help with bash
Using Mac OS 10.15.x Catalina

Consider the following CSV:

Code:
Name Error Count Severity Info
Server1 not found 1025 MAJOR some info here
Server4 some error 1 MAJOR some info here
Server 2 another error 587 MINOR more info
Server3 not found 15 MAJOR more info

I have some code to sort on the Severity, however, I can't get the numerical sort on the count to work correctly. I try to sort it numerically first, and then by severity, but the numerical portion doesn't seem to work. Here is what I have:

Code:
sort -k3,1 "$1";( grep -i "name" "$1"; grep "CRITICAL" "$1"; grep "MAJOR" "$1"; grep "HIGH" "$1"; grep "MEDIUM" "$1"; grep "MINOR" "$1"; grep "LOW" "$1" | sort ) > $OUT

RESULTS: It sorts on severity just fine, but doesn't sort on Count. Let me know if that doesn't make sense.

Desired outcome (notice the Count is from greatest to least within each sub-set of Severity)
Code:
Name Error Count Severity Info
Server1 not found 1025 MAJOR some info here
Server3 not found 15 MAJOR more info
Server4 some error 1 MAJOR some info here
Server 2 another error 587 MINOR more info

mknod

MKNOD(1)							   User Commands							  MKNOD(1)

NAME

       mknod - make block or character special files

SYNOPSIS

       mknod [OPTION]... NAME TYPE [MAJOR MINOR]

DESCRIPTION

       Create the special file NAME of the given TYPE.

       Mandatory arguments to long options are mandatory for short options too.

       -m, --mode=MODE
	      set file permission bits to MODE, not a=rw - umask

       -Z, --context=CTX
	      set the SELinux security context of NAME to CTX

       --help display this help and exit

       --version
	      output version information and exit

       Both  MAJOR and MINOR must be specified when TYPE is b, c, or u, and they must be omitted when TYPE is p.  If MAJOR or MINOR begins with 0x
       or 0X, it is interpreted as hexadecimal; otherwise, if it begins with 0, as octal; otherwise, as decimal.  TYPE may be:

       b      create a block (buffered) special file

       c, u   create a character (unbuffered) special file

       p      create a FIFO

       NOTE: your shell may have its own version of mknod, which usually supersedes the version described here.  Please refer to your shell's doc-
       umentation for details about the options it supports.
