The order depends on how the sender put the lines. Try
Code:
awk '
BEGIN           {for (MX=i=split ("From To: Subject: Message-ID: Date:", KEYS); i>0; i--) VALS[KEYS[i]]
                }

function prtit()        {printf "\n"
                         for (i=1; i<=MX; i++) print VALS[KEYS[i]]
                        }

$1 in VALS      {if ($1==KEYS[1] && NR>1) prtit()
                 VALS[$1]=$0}

END             {prtit()}
' /home/...default/Mail/Local\ Folders/Inbox

mail::message::body::string

Mail::Message::Body::String(3pm)			User Contributed Perl Documentation			  Mail::Message::Body::String(3pm)

NAME

       Mail::Message::Body::String - body of a Mail::Message stored as single string

INHERITANCE

	Mail::Message::Body::String
	  is a Mail::Message::Body
	  is a Mail::Reporter

SYNOPSIS

	See Mail::Message::Body

DESCRIPTION

       The body (content) of a message can be stored in various ways.  In this documentation you will find the description of extra functionality
       you have when a message is stored as a single scalar.

       Storing a whole message in one string is only a smart choice when the content is small or encoded. Even when stored as a scalar, you can
       still treat the body as if the data is stored in lines or an external file, but this will be slower.

DIAGNOSTICS

       Warning: Charset $name is not known
	   The encoding or decoding of a message body encounters a character set which is not understood by Perl's Encode module.

       Warning: No decoder defined for transfer encoding $name.
	   The data (message body) is encoded in a way which is not currently understood, therefore no decoding (or recoding) can take place.

       Warning: No encoder defined for transfer encoding $name.
	   The data (message body) has been decoded, but the required encoding is unknown.  The decoded data is returned.

       Error: Package $package does not implement $method.
	   Fatal error: the specific package (or one of its superclasses) does not implement this method where it should. This message means that
	   some other related classes do implement this method however the class at hand does not.  Probably you should investigate this and
	   probably inform the author of the package.

       Error: Unable to read file $filename for message body scalar: $!
	   A Mail::Message::Body::String object is to be created from a named file, but it is impossible to read that file to retrieve the lines
	   within.

       Warning: Unknown line terminator $eol ignored
