If memory serves right you will need to change the location of the $postrow[$i]['UserStatus'] in the showflat.tmpl and position it below the location.
So the:
<b>{$postrow[$i]['Username']}{$postrow[$i]['UserStatus']}</b>
<br />
<span class="small">
{$postrow[$i]['Title']}
<br />
{$postrow[$i]['Rating']}
<br />
{$postrow[$i]['Picture']}
<br />
{$postrow[$i]['Registered']}
<br />
{$postrow[$i]['TotalPosts']}
<br />
{$postrow[$i]['Location']}
will become:
<b>{$postrow[$i]['Username']}</b>
<br />
<span class="small">
{$postrow[$i]['Title']}
<br />
{$postrow[$i]['Rating']}
<br />
{$postrow[$i]['Picture']}
<br />
{$postrow[$i]['Registered']}
<br />
{$postrow[$i]['TotalPosts']}
<br />
{$postrow[$i]['Location']}
<br />
{$postrow[$i]['UserStatus']}
Similarly for showthreaded you need to change this:
<b>$Username$MainUserStatus</b>
<br />
<span class="small">
$Title
<br />
$Rating
<br />
$Picture
<br />
$Registered
<br />
$TotalPosts
<br />
$Location
</span>
to this:
<b>$Username</b>
<br />
<span class="small">
$Title
<br />
$Rating
<br />
$Picture
<br />
$Registered
<br />
$TotalPosts
<br />
$Location
<br />
$MainUserStatus
</span>
With this approach you can use a bit bigger graphics
