However, what I want it to do now, instead of just putting the number into the attribute value, I want the number to be a suffix to the existing default tag value of the tag named "ID" which is "ADDRESS:" for some blocks and "ELEVATION:" for other blocks but the tag name that the routine always has to filter for is "ID".

Yes, I’m a little confused by your brief too. The script that I describe here will create an array of numbers using any step value that it offers, including by 1 number each time. Whether you put the resulting list directly into InDesign as text, or indirectly using the Data Merge feature is up to you. Perhaps learn more about the Data Merge feature of InDesign itself – David Blatner has a great series on Lynda.com that will explain Data Merge much more than I can on this thread.
If the second number on your raffle ticket is one higher than the first number, you must have accidentally put the <> tag after the first number (causing the next number, on the same ticket, to increase by one). You only need the <> after the second number on each ticket, so the next ticket gets a new number. (But you don't need it on the final ticket on the **page**, because the next **page** automatically gets a new number) sequential numbering using publisher
