In my experience, cfengine treats $(string) first checks to see whether
string is a variable name, and if so, it replaces $(string) with the
value of the variable, otherwise the output of treating string as a
command.  bits is a variable name, so $(bits) is replaced with "exec
/usr/bin/isainfo -kv | cut -b1-2".  I think maybe you should try this
instead:

           bits = ( "$(exec /usr/bin/isainfo -kv | cut -b1-2)" )
