How about using map to construct a list of tags and then change the default list separator to the pipe symbol and just print the array.

#!/usr/bin/perl -l
#
use strict;
use warnings;

use CGI qw/:all *table'/;
use English q{-no_match_vars};

my %sections = (
   q{ DMA} => q{dma},
   FST     => q{dma/fst},
   MRA     => q{dma/mra},
   BKS     => q{bks},
   MSU     => q{dma/msu},
   FMA     => q{dma/fma},
   FOMC    => q{dma/FOMC});

print q{<h3 align='center'>};

my @aTags =
   map { a({-href => qq{/$sections{$_}}}, qq{$_ HOME}) }
   sort keys %sections;

{
    local $LIST_SEPARATOR = q{|};
    print qq{@aTags};
}

print q{</h3>};

Here's the output, the script runs with the -l flag.

<h3 align='center'>
<a href="/dma"> DMA HOME</a>|<a href="/bks">BKS HOME</a>|<a href="/dma
+/fma">FMA HOME</a>|<a href="/dma/FOMC">FOMC HOME</a>|<a href="/dma/fs
+t">FST HOME</a>|<a href="/dma/mra">MRA HOME</a>|<a href="/dma/msu">MS
+U HOME</a>
</h3>

This seems to do what you want.

Cheers,

Update: Added output.
