Because they measure different things.

What is the value 1251 and 6 from ls cmd in fifth column ? (I guess Bytes)
1251 is indeed bytes but 6 represent a number of entries (links) and not bytes as "scripts" is a directory.
Quote:
If those values represent Bytes, why is the difference between 'ls -la' and 'du -sh *' outputs ?
"du" reports the size the file takes on the disk. This size depends on the file system used. "ls" reports the file size. They are somewhat related but different metrics. You certainly can have a file size larger that the space it takes on disk.

NAME
App::Cmd::Command::commands - list the application's commands VERSION
version 0.318 DESCRIPTION
This command plugin implements a "commands" command. This command will list all of an App::Cmd's commands and their abstracts. METHODS
execute This is the command's primary method and raison d'etre. It prints the application's usage text (if any) followed by a sorted listing of the application's commands and their abstracts. The commands are printed in sorted groups (created by "sort_commands"); each group is set off by blank lines. "sort_commands" my @sorted = $cmd->sort_commands(@unsorted); This method orders the list of commands into sets which it returns as a list of arrayrefs. By default, the first group is for the "help" and "commands" commands, and all other commands are in the second group. AUTHOR
