Further to previous post: A solution using a regex per OP request. No hashes. Note that the function now takes two strings, not a string and a hash. Tested, works. 

sub scrabblicious {

    my ($word,  # word to test for scrabble match to tray of letters
        $tray,  # string with 'tray' of letters to select from
        ) = @_;

    return if not length $word;  # special case: empty string

    $tray =~ s/$_//xms or return for map quotemeta, split '', $word;

    return 1;

    }

Update: Instead of
    $tray =~ s/$_//xms or return for map quotemeta, split '', $word;
using
    $tray =~ s/\Q$_\E//xms or return for split '', $word;
might be slightly faster because it avoids having  map quotemeta build another intermediate array. (Tested.)
