You'll need the editheader extension (meaning a fairly new Pigeonhole 
v0.3.0+):

require ["fileinto", "editheader", "variables", "regex"];

if address "sender" "owner-scientific-linux-devel at LISTSERV.FNAL.GOV" {
   if header :regex "subject" "\\[SCIENTIFIC-LINUX-DEVEL\\] *(.*)" {
     deleteheader "Subject";
     addheader "Subject" "${1}";
}

    addheader "List-Post" "<mailto:scientific-linux-devel at fnal.gov>";

    fileinto "Mail List.SL-Devel";
}

require ["fileinto", "editheader", "variables", "regex"];

if header "X-BeenThere" "users at lists.repoforge.org" {
   if header :regex "subject" "\\[users\\] *(.*)" {
     deleteheader "Subject";
     addheader "Subject" "${1}";
   }
   fileinto "Mail Lists.RPMForge";
}


Don't forget to enable the editheader extension in your configuration 
using the sieve_extensions setting.
