$_ contains an array ref. It loops through each entry in the array ref. If
the entry is a number (by the above regexp's naive view of numbers), it
maps it to <td align="right">number</td>, otherwise it maps it to
<td>value</td>.
The use of $_ as the container for the array ref, while using map (which
gives you a $_ inside the map expression) is scary scary obfuscated
nastiness and deserves a slap for whoever wrote it.
