Help with BASH/AWK queries ....

Hi Everyone,

I have an input file in the following format:
score.file1.txt
HTML Code:
contig00045 length=566   numreads=19    1047    0.0
contig00055 length=524   numreads=7    793    0.0
contig00052 length=535   numreads=10    607    e-176
contig00072 length=472   numreads=46    571    e-165
contig00019 length=667   numreads=5    474    e-136
I've a second file:
data.file1.txt
HTML Code:
>contig00045 length=566   numreads=19
GGGCTGACGTGCCGCTAATACGACTCACTATAGGGAGAGCATAAAACACG
CCTCCTGAGCTGCAGCAGAAAAAGAGACTCCCCTTGAGCTTTCAGATTGA

>contig00019 length=667   numreads=5

GCTGACCGTCCCATGTAAGGGTGGTGTCGGAT
This file contains a header (>contig00045 length=566 numreads=19) followed by few lines of sequence.

In the first file (score.file1.txt), for each row the fourth column is score1(1047, 793, 607,571 etc.) and 5th column is score2 (0.0, 0.0, e-176, e-165 etc.).
I would like to extract those TWO data (from data.file1.txt) based on TOP score1 and if their score2 is NOT 0.0.

For example based on the above data, my desired output is:
output.file1.txt
HTML Code:
>contig00052 length=535   numreads=10
GGGCTGACGTGGCCGCTAATACGACTCACTATAGGGAGAGGGATGTCCAC
AGGCAGAGGGATGTCCACAGGCAGAGGGATGCCACAGGCA
>contig00072 length=472   numreads=46

Thanks in advance.
