Does the pressure of the heat source in an organic rankine cycle have to be higher than that of the working fluid?

 

It seems so from the temperature-entropy diagram of the cycle. I just wanted to make sure.

No.  Only the temperature must be higher.

but there is a direct relation between temperature and pressure. In addition, on a T-S diagram the line presenting the heat source would be above that of the working fluid due to its higher temperature, this should mean that it is on a higher isobar, right?

No.  Because the two fluids NEVER mix, only temperature governs heat transfer directionality.
