Why did you make it so complicated?  What's wrong with simply:

    alias l='ls -lF|more -e'

or perhaps:

    export MORE=-e
    alias l='ls -lF|more'

And by the way, this line:

    if [[ $more_version -ge 2.38 ]]

is not correct.  Bash can't do a floating point numeric comparison.  This
syntax simply gives an error message:

hobbit:~$ [[ 2.1 -ge 2.2 ]]
bash: [[: 2.1: syntax error: invalid arithmetic operator (error token is ".1")

Are you using some other shell, maybe?  Like zsh?
