For above sample, this should do
Code:
awk     '       {printf "%s ", $0
                 FN=$1; ST=$2; EN=$3;
                 while ($1+0 < EN)      {getline < FN
                                         if ($1 >= ST) sum+=$2}
                                         printf "%s\n", sum
                                         sum=0}
        ' file
A1  3  5 0.909
A1  7  9 0.65
A2  2  5 0.9
A3  1  3 0.8

It is not aimed at nor tested for severely different input data.
