Although from your question it is a bit unclear what you are looking for, perhaps the following code segment will help.

#/usr/bin/perl -w
use strict;
foreach (sort split /\s+/,<DATA>) {
    /^\d/ ? print "FH1: $_\n" : print "FH2: $_\n";
}

__DATA__
953-FMT-FMT   954-FMT-FMT   BLOGO93-FMT-FMT   955-FMT-FMT   BOXSTART2-
+FMT-FMT   BOXEND2-FMT-FMT   956-FMT-FMT   413-FMT-FMT   DATE1-FMT-FMT
