BASH: Sort four lines based on first line

I am in the process of sorting an AutoHotkey script's contents so as to make it easier for me to find and view its nearly 200 buzzwords (when I forget which one corresponds with what phrase, which I do now and then).

About half to two-thirds of the script's key phrases correspond to locations (see example data). These are the ones I've been trying to sort first.

My data looks like this:
Code:
;Canyon
::grand::
Send, Canyon
Exit

;Elevator
::lift::
Send, Elevator
Exit

;Office
::9to5::
Send, Office
Exit

;Cabin
::log::
Send, Cabin
Exit

;Desert
::sahara::
Send, Desert
Exit

;Front door
::welcome::
Send, Front door

In order for this data to work in the AHK script once it's sorted, it has to remain multi-line. I admit I'm somewhat bummed because the sort command works line-by-line and is not appropriate for what I want to do.

So what would be a good method for sorting just these groups of 4 lines (for example), by the first line in each one, as they stand?

NAME
members - outputs members of a group SYNOPSIS
members groupname DESCRIPTION
This manual page documents briefly the members commands. This manual page was written for the Debian GNU/Linux distribution. members is a program that sends a space-separated list of secondary member names to its standard output. OPTIONS
The programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. -a, --all Show all group members on one line. This is the default. -p, --primary Show only primary group members. -s, --secondary Show only secondary group members. -t, --two-lines Send two lines to standard output. First line is primary members, second line is secondary members. NOTE: This always displays two lines, even if there are no members at all. -h, --help Show summary of options. DIAGNOSTICS
Exit status is 0 (i.e. "success") if the group was found, and 1 (i.e., "failure") if the group was not found. Technically, the exit status hinges on the output of getgrnam(3) as follows: if getgrnam(3) returns a null pointer, the exit status is 1, and 0 otherwise. BUGS
I don't know of any! If you find one, please let me know! SEE ALSO
