a different letter prefix for each set, i.e., a001..a300.txt and b001..b300.txt. I only want the numbers starting with a to increase without changing b. Where should I specify/add this prefix?
In other words, the actual lines look more like this:
As you can see, the current script would change the numbers for a (as intended) but also the corresponding number for b.

Not sure I get it - do you want the "a" numbers modified in the the file, or work on the file names starting with "a" only? I case of the former, try gsub (/a001/, "a" TCNT, T), in case of the latter, try a*.txt for the file name parameter.

SC_TRACEDIFF(1) BSD General Commands Manual SC_TRACEDIFF(1)NAME
sc_tracediff -- display traceroute paths where the path has changed.
SYNOPSIS
sc_tracediff [-a] [-m method] [-n] file1.warts file2.warts
DESCRIPTION
The sc_tracediff utility displays pairs of traceroutes to a destination where the path has changed. It takes two warts files as input and
displays paths where a hop differs by its address. The options are as follows:
-a dump all traceroute pairs regardless of whether they have changed.
-m method
specifies the method used to match pairs of traceroutes together. If dst is specified, traceroutes are matched if the destination IP
address of both traces are the same. If userid is specified, traceroutes are matched if the userid field of both traces are the
same. If dstuserid is specified, traceroutes are matched if the destination IP address and userid fields are the same. By default,
the destination IP address is used.
-n names should be reported instead of IP addresses, where possible.
sc_tracediff can be useful in network monitoring to identify when a forward IP path has changed. In this scenario, it is recommended that
Paris traceroute is used with the same UDP source and destination ports for each execution of scamper so that only paths that have changed
are identified, not merely alternate paths visible due to per-flow load-balancing. By default scamper uses a source port based on the
process ID, which will change with each execution of scamper.
EXAMPLES
The command:
scamper -O warts -o file1.warts -c 'trace -P udp-paris -s 31337' -f list.txt
collects the forward IP paths towards a set of IP addresses found in list.txt using 31337 as the UDP source port value. If the above command
is adjusted to subsequently collect file2.warts, then we can identify paths that have subsequently changed with the command:
sc_tracediff file1.warts file2.warts
If Paris traceroute with ICMP probes is preferred, then the following invocation of scamper is appropriate:
scamper -O warts -o file1.warts -c 'trace -P icmp-paris -d 31337' -f list.txt
In this case, scamper uses 31337 as the ICMP checksum value in each probe.
