You're pretty close. Try something like this:

when HTTP_REQUEST {
    if { [HTTP::header exists AKAMAI_HEADER] } {
        if { [class match [HTTP::header AKAMAI_HEADER] equals my_data_group] } {
            set state [class match -value [HTTP::header AKAMAI_HEADER] equals my_data_group]
            switch $state {
                "value1" { }
                "value2" { }
                default {
                     what do you do if the data group value doesn't match one of your switch states?
                }
            }
        } else {
             what do you do if the AKAMAI header doesn't match a data group entry?                
        }
    } else {
         what do you do if the AKAMAI header doesn't exist?
    }
}
