You could strip all but the numbers from the strings first and then compare like this example:

Code:

$ echo V_1_4_4_b1 V_1_5_1_RC_b1 | tr -d '[:alpha:]_'
1441 1511

tiff2rgba

TIFF2RGBA(1)						      General Commands Manual						      TIFF2RGBA(1)

NAME

       tiff2rgba - convert a TIFF image to RGBA color space

SYNOPSIS

       tiff2rgba [ options ] input.tif output.tif

DESCRIPTION

       Tiff2rgba  converts  a  wide variety of TIFF images into an RGBA TIFF image.  This includes the ability to translate different color spaces
       and photometric interpretation into RGBA, support for alpha blending, and translation of many different bit depths into a 32bit RGBA image.

       Internally this program is implemented using the TIFFReadRGBAImage() function, and it suffers any limitations of that image.  This includes
       limited support for > 8 BitsPerSample images, and flaws with some esoteric combinations of BitsPerSample, photometric interpretation, block
       organization and planar configuration.

       The generated images are stripped images with four samples per pixel (red, green, blue and alpha) or if the -n flag is used, three  samples
       per  pixel  (red,  green,  and blue).  The resulting images are always planar configuration contiguous.	For this reason, this program is a
       useful utility for transform exotic TIFF files into a form ingestable by almost any TIFF supporting software.

OPTIONS

       -c     Specify a compression scheme to use when writing image data: -c none for no compression (the default), -c packbits for the  PackBits
	      compression algorithm, -c zip for the Deflate compression algorithm, -c jpeg for the JPEG compression algorithm, and -c lzw for Lem-
	      pel-Ziv & Welch.

       -r     Write data with a specified number of rows per strip; by default the number of rows/strip is selected so that each strip is approxi-
	      mately 8 kilobytes.

       -b     Process the image one block (strip/tile) at a time instead of by reading the whole image into memory at once.  This may be necessary
	      for very large images on systems with limited RAM.

       -n     Drop the alpha component from the output file, producing a pure RGB file.  Currently this does not work if the -b flag  is  also	in
	      effect.
