ClassMethod SortVersion(input As%String[]) As%String[] {
    Set sorted = []

    for i=1:1:input.%Size() {
        Set version = input.Get(i)

        Set major = $NUMBER($PIECE(version, ".", 1))
        Set minor = $NUMBER($PIECE(version, ".", 2))
        Set patch = $NUMBER($PIECE(version, ".", 3))

        // Create a new dynamic object to store the version number and its corresponding string representationSet versionObj = {}
        Set versionObj.version = version
        Set versionObj.major = major
        Set versionObj.minor = minor
        Set versionObj.patch = patch

        // Add the version object to the 'sorted' arrayDo sorted.Insert(versionObj)
    }

    // Sort the 'sorted' array based on major, minor, and patch valuesDo sorted.Sort("major", "minor", "patch")

    // Create a new array to store the sorted version numbersSet sortedVersions = []

    // Iterate over the sorted objects and extract the version numberFor i=1:1:sorted.%Size() {
        Set versionObj = sorted.GetAt(i)
        Do sortedVersions.Insert(versionObj.version)
    }

    Quit sortedVersions
}

Seems to make sense.  Usage is:

Set input = ["1.4.5", "0.5.3", "6.3.2", "1.2.4"]
Set sortedVersions = ##class(YourClassName).SortVersion(input)
Write !, sortedVersions.%ToString()

This documentation shows how to connect and interact with IRIS using Python.  Following this worked for me:

https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cl…

Using port 1972 per the example worked in my case but your installation may vary.  It requires Python 3 (3.4+).  When you download the Intersystems wheel file, make sure that the filename remains unchanged otherwise pip won't be able to install it.
