May I ask why file1 defines multiple but contiguous intervals which could be done in a single line defining min and max? E.g. 10 - 20, 20 - 30, and 30 - 40 could be condensed to 10 - 40 for Sc1 (which is what Scrutinizer's code does internally, assuming as well that intervals come in ascending order).
Would it be correct to assume that multiple interval definitions are to allow gaps between intervals? If yes, try (with e.g. the Sc1 20 30 line missing in the sample file)

Code:

awk -F"\t" '
NR == FNR       {INT[$1] = INT[$1] $2 "-" $3 FS
                 next
                }
                {split (INT[$1], T)
                 OUT = "NA"
                 for (t in T)   {split (T[t], LM, "-")
                                 if ($2 >= LM[1] && $2 < LM[2]) OUT = $4
                                }
                 print OUT
                } 

' file1 file2
NA
NA
25
40
NA
NA

With file1 from post#1, it's

Code:

100

xzdiff

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME

       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION

       xzcmp  and  xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options specified are passed
       directly to cmp or diff.  If only one file is specified, then the files compared are file1 (which must have a suffix of	a  supported  com-
       pression  format)  and  file1 from which the compression format suffix has been stripped.  If two files are specified, then they are uncom-
       pressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp or diff is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO

       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1)

BUGS

       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
