If it works and it is readable, I wouldn't be too concerned about a few for loops. That said, I'd probably do two things: use hash slices (see perldata) instead of all of the individual $data{key} = $_->key; statements, and pull the guts of the for ( @info ) loop into a subroutine (since you use it twice). For example (untested):

for ( @info )
{
    push( @loop_data, get_info( $_ ) );
}

sub get_info
{
    my ( $info ) = @_;

    my $sth = $obj->DBI->Replies->sql_count;
    $sth->execute( $info->id );
    my $info->count = ( $sth->fetchrow_array )[0];

    my @keys = qw( author content title id date count );
    my %data;
    @data{ @keys } = @$info{ @keys };

    return \%data;
}

Note: I changed $r to $info->count to clean up the hash slice. Update: Corrected $count to $info->count.

HTH, and congrats on getting it working. That's the first step. :-)
