Thank you all very much for your helpful suggestions. I combined them to form the following (which even (accidentally) managed to beat Ovid's by a hair):
mkmcconn: 4 wallclock secs ( 4.66 usr + 0.00 sys = 4.66 CPU) @ 1073.88/s (n=5000)
ovid: 7 wallclock secs ( 7.10 usr + 0.00 sys = 7.10 CPU) @ 704.13/s (n=5000)
@result1 = map{join '',@$_[0..4,6,8]}
sort{
$a->[8] cmp $b->[8]
||
($b->[7] eq '' ? 0 : $b->[7]) <=> ($a->[7] eq '' ? 0 : $a->[7]
+) # didn't manage to eliminate this without warnings
||
$a->[0] <=> $b->[0]
||
$a->[1] cmp $b->[1]
||
$a->[2] <=> $b->[2]
||
$a->[5] <=> $b->[5]
||
$a->[3] cmp $b->[3]
} map {[m/(\d+)(\D+)(\d+)(\D*)(R(\d+))(B?(\d*))(\.\w+)\s*$/] } <DATA
+>;

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
