Indeed. set is not allowed at the http level, although it could be
quite useful IMHO. Either that or allowing to combine variables as the
left side of the map.

You have to do a more complex mapping. Remove the set and use the
following map instead (while mantaining the if at the server level):

map $query_string $new_uri {
    option=com_content&view=category&id=40&Itemid=106 /blahblah/page1;
    option=com_content&view=article&id=164&Itemid=139 /blahblah/page2;
    ## add as query string -> new uri lines as needed.
}

Now it depends on the order, which is bad. Other option is to use only
set and if. Like this:

At the server level:

## String composed of all the arguments on the URI.
set $arg_str $arg_option$arg_view$arg_id$arg_itemid;

if ($arg_str = com_contentarticle40106) {
   rewrite ^ $scheme://$host/blahblah/page1 permanent;
}

if ($arg_str = com_contentarticle164139) {
   rewrite ^ $scheme://$host/blahblah/page2 permanent;
}

Add as many if blocks as needed.

It's ugly but since you have only a few redirects, it's manageable
IMHO. Now you no longer depend on the order.
