Abigail-II's solution fails for the last string because of the empty entry E. Here's another way to parse this: 

my @accounts = (
    "A x1 B y1 C z1 D v1 E w1 F", 
    "A x2 B y2 C zzz2 D v2 E w2 F", 
    "A x3 B y3 C z3 D v3 E w3 F", 
    "A x4 B y4 C z4 D v4 E wwww4 F",
    "A x5 B y5 C z5 D v5 E w5 F", 
    "A x6 B y6 C z6 D v6 E    F",
);

# Transform @accounts in place
for (@accounts) {
    tr/ //d;                    # get rid of those confusing spaces
    my @acct = split /([A-F])/; # use the tags
    shift @acct;                # get rid of the undef pre-A entry...
    pop @acct;                  # ... and the 'F'
    my %stuff = (@acct);        # hash what's left
    $_ = [@stuff{'A'..'E'}];    # keep ordered values
}

{
    local $" = "\t";
    print "|@$_|", $/ for @accounts;
}
__END__
|x1    y1    z1    v1    w1|
|x2    y2    zzz2    v2    w2|
|x3    y3    z3    v3    w3|
|x4    y4    z4    v4    wwww4|
|x5    y5    z5    v5    w5|
|x6    y6    z6    v6    |

The transformation of @accounts could be shortened a lot, but I wanted to show it step-by-step for clarity. Your data format is not of the handiest.
