If you are talking version numbers your probably better off converting and comparing numerically.

set num=*get field from user agent*
foreach {major minor sub} [split $num "."] break;

if { $major < 7 } {
  if { $minor < 1002 } {
     if { $sub < 145 } {
         reject
         log local0. "reject reason"
     }
  }
}

If however the version number is numerically valid.. 

if {$version < 1006.145} {
   reject
}
