Sort table and make schedule from script

[Tue]

Hello there

I have a table looeking like this (but up to 40 lines):
local tbl = {
{month = 2, day = 13, hour = 9, price_raw = 0.12 , price_total= 0.42},
{month = 2, day = 13, hour = 10, price_raw = 0.22 , price_total= 0.49},
{month = 2, day = 13, hour = 11, price_raw = 0.23 , price_total= 0.43},
{month = 2, day = 13, hour = 12, price_raw = 0.11 , price_total= 0.44},
{month = 2, day = 13, hour = 13, price_raw = 0.13 , price_total= 0.48},
{month = 2, day = 13, hour = 14, price_raw = 0.19 , price_total= 0.38},
{month = 2, day = 13, hour = 15, price_raw = 0.14 , price_total= 0.41},
{month = 2, day = 13, hour = 16, price_raw = 0.16 , price_total= 0.28}
}

How do I sort the table after [price_total] ?

Now I want to make a Schedule, lets call them, Charge_ev_in_min

How do I edit a schedule from script? I need to do the following:
Set time and date for start
Set value (0-600)
Disable scheduler
Enable scheduler
delete schedule
