Well, it is (kind of). ;)
I ended up using regexp to do it:
<!--#if expr="$map == /^\/boletines\/(\\d{4})\/(\\d+)/" -->
<!--#set var="mapYear" value="$1" -->
<!--#set var="mapNumber" value="$2" -->
<!--#endif -->
<!--#if expr="$REQUEST_URI == /^\/boletines\/(\\d{4})\/(\\d+)/" -->
<!--#set var="year" value="$1" -->
<!--#set var="number" value="$2" -->
<!--#endif -->
<ul>
<!--#if expr="$year=$mapYear && $number=$mapNumber" -->
...
