Shell's `RANDOM` is not determined by seed when used with `awk`

Consider the following shell script, and the output that follows...

#!/bin/bash

RANDOM=5

for i in {0..9..1}
do
        rand_val=$(awk -v rand_awk=$RANDOM 'BEGIN{print rand_awk;}')
        echo "generated $RANDOM"
        echo "generated in awk: $rand_val"
done

It looks like inside awk statement, the numbers generated by RANDOM are not affected by the seed (5). I want rand_val to also be effected by the seed that RANDOM gets, mainly because I want to use awk's rand() function in a predictable way:

#!/bin/bash

RANDOM=5
RANGE=3

for i in {0..9..1}
do
        rand_val=$(awk -v rand_awk=$RANDOM -v range=$RANGE 'BEGIN{srand(rand_awk); print rand()*range;}')
        echo "generated in awk: $rand_val"
done
