macOS AppleScript Decimal Numbers

[gpchess2k]

Hello, everyone! Im trying to do a simple script where it pulls the version number of an app and checks to see if its less than. I dumbed down the script down below. AppleScript only looks at the first number after the decimal place to determine what's greater. In the example below, 4.17.9 is greater than 4.17.10.

tell application "System Events"
    set driverVersion to "4.17.9"
    if driverVersion < "4.17.10" then
        display dialog "OLDER"
    else
        display dialog "NEWER!"
    end if
end tell

Not AppleScript but...

BOOL runningOnAtleast(int majorVersion, int minorVersion, int patchVersion)
{
    NSOperatingSystemVersion OSVersion; //struct with three variables declared as NSIntegers:
    OSVersion.majorVersion = majorVersion;
    OSVersion.minorVersion = minorVersion;
    OSVersion.patchVersion = patchVersion;
    return [[NSProcessInfo processInfo] isOperatingSystemAtLeastVersion: OSVersion];
}

Thanks for the response but I do need a solution for AppleScript specifically.

Normally strings are compared according to their character values, but for comparing them numerically you can use a considering statement, for example:

set driverVersion to "4.17.9"
considering numeric strings
    if driverVersion < "4.17.10" then
        display dialog "OLDER"
    else
        display dialog "NEWER!"
    end if
end considering
