The string expansion filter page explained it quite well:

Standard RegEx: \s{25,}
Exim filter: \\s{25,}
quoted Exim filter: \\\\s{25,}

You may want to adjust your filter to:

$header_subject matches "\\\\s{25,}\\\\[?\\\\w{3,}\\\\]?\\$"

It will match the [ ] and a standard alphanumeric code. This thing's
