awk based solution
Code:
 
 $ cat test.sh
 awk '
{
        if (NR == FNR)  ### reading 1st file
                        ### accumulate 2nd column values in array of key values
        {
                arr[NR] = $2;
        }
        else            ### reading 2nd file and check for value of 2nd column
                        ### to be within +/- 500 of any accumulated key values
        {
                maxval = $2 + 500;
                minval = $2 - 500;
                for ( x in arr )
                {
                        if(minval <= arr[x] && arr[x] <= maxval)
                                print $0;
                }
         }
}
' $1 $2

Here is how I ran it
Code:
 
 $ cat a
1       11567687        snpid20
1       153881  snpid1
2       56768799        snpid7
3       3156760 snpid4
3       1567687 snpid7
$ cat b
1       11567600        snpid20
3       1000000 snpid7
 $ test.sh b a
 1       11567687        snpid20

hope this is what you were looking for
