Groovy: How to sort array of text and numbers by numbers in middle

I have an array like this:

def array = [ 
  "release-3.0.0-1-a6gbd6",
  "release-3.0.0-10-h7bdbc",
  "release-3.0.0-12-7hbs6",
  "release-3.0.0-23-9sz6gd",
  "release-3.0.0-3-g6h8xd",
]

I need it to be able to sort it by numbers in the middle (e.g. 3.0.0-1) in reverse order to look like this:

def array = [ 
  "release-3.0.0-23-9sz6gd",
  "release-3.0.0-12-7hbs6",
  "release-3.0.0-10-h7bdbc",
  "release-3.0.0-3-g6h8xd",
  "release-3.0.0-1-a6gbd6",
]

How can I do this with Groovy?

I tried following Groovy: How to sort String array of text+numbers by last digit but am not having any luck

This appears to be working

def newArray = array.sort(false){[it.tokenize('-')[-3], it.tokenize('-')[-2] as Integer]}

Here we are sorting on the string after the first dash, and then sorting by the integer after the second dash
