I don't think there will be that many SC people with a better mark thanks you. So Congratulations. You should be getting any direct admissions possible. Might need to wait for 2nd or 3rd list -- but no price for it.
Also really happy with your score because I see some SC people asking me I'm SC and what is the minimum mark needed to get IITs and then again asking if I mug up only these and so will I get that. Most of them won't even qualify GATE is the reality. Prepare like anyone and when you get privilege of being in a community -- take it. That's what everyone should do.
To be clear to your exact question you should apply to IISc CSA TA and IITB TA and you should be getting both or at least one.
