Help sorting metric results for honeycomb

I have dashboards monitoring the health of our systems with a honeycomb "traffic light grid" shown below.
The metric query I use for this is :-

dbidentifier=(*) _collector=redacted metric=CPUUtilization statistic=average 

I want to be able to sort my honeycomb based on the dbidentifier value, so they are consistent and alphabetical. I assumed I could just add | sort by dbidentifier but doing that gives me a syntax error. 

syntax error: [2.3] failure: 
Expected start of an operator from the list {avg, sum, min, max, count,
 pct, quantize, timeshift, histogram_quantile, timeslice accumulate, 
parse, rate, delta, eval, topk, bottomk, filter, fillmissing, outlier}, 
but 's' found | sort by dbidentifier ^.

Can anybody help me with fixing this as it helps greatly with readability when I have a honeycomb of over 100 servers and I'm looking for a specific one.
