The EBV and CMV wouldn't factor in, but at a 2.72, even with the positive additional test, can still be a false positive. Anything under a 3.5 can be.
The closer it is to a 3.5, the better the chances that it isn't, but the chances are about 50/50, maybe a little worse, that it's actually positive.
Usually, the reflex or supplemental tests are the exact same tests, which doesn't really tell us much.
You can have a Western Blot test done to confirm this. Your doctor can order it, or you can go through Terri Warren at the Westover Heights Clinic, but you'll have to self-pay.
Having hsv1 can make hsv2 mild, so not having severe symptoms doesn't mean much here. The number means the most. How long has it been since your most recent possible exposure? (Oral sex isn't really a risk for hsv2, since oral hsv2 is really pretty rare.)
The symptoms you had could still be balanitis or a fungal infection. It doesn't mean those symptoms were herpes, even if you have it.
If you need to talk to your doctor about getting the Western Blot, show them this:
"The most commonly used test, HerpeSelect HSV-2 Elisa might be falsely positive at low index values (1.1–3.5) (334-336). Such low values should be confirmed with another test, such as Biokit or the Western blot (337). The HerpeSelect HSV-2 Immunoblot should not be used for confirmation, because it uses the same antigen as the HSV-2 Elisa. Repeat testing is indicated if recent acquisition of genital herpes is suspected. "
If your doctor is testing for and treating STDs, they should be familiar with and adhering to the CDC's STD Treatment Guidelines. (I'm assuming you're in the US because of the ease in which you got the blood testing. If you aren't, let me know.)

I don't want to give you false hope - there is definitely a chance that you have hsv2. If you do, we'll get you through that. This is all going to take time, though. While you wait, you can read the Herpes Handbook - https://westoverheights.com/herpes/the-updated-herpes-handbook/
