The difference between WMS 1.1.1 and 1.3.0 is two fold.
CHANGE NO 1 - CRS/SRS Usage
Use SRS for 1.1.1
Use CRS for 1.3.0
CHANGE No 2 - WMS 1.3.0 ONLY
The order of parameters for BBOX depends on whether the CRS definition has flipped axes. You will see this in the GetCapabilities request at 1.3.0 - the response should show the flipped axes.
BBOX=xmin,ymin,xmax,ymax NON-FLIPPED
BBOX=ymin,xmin,ymax,xmax FLIPPED
I have made a list of EPSG codes that need to be flipped by creating a SpatiaLite 4.3.0 database and then saving this SQL request to file:
SELECT auth_srid, has_flipped_axes, ref_sys_name, axis_1_name, axis_1_orientation, axis_2_name, axis_2_orientation FROM "spatial_ref_sys_all" WHERE auth_name = "epsg";
You will then see that EPSG:4326 needs to have flipped axes.
4326 1 WGS 84 Latitude North Longitude East
THIS IS THE CORRECTED 1.3.0 REQUEST
Change is BBOX=24,-126,50,-66

My original answer is below the line but I am having second thoughts about it. This is because the ArcGIS Server 10 Help page entitled Customizing a WMS GetFeatureInfo response says:
ArcGIS Server comes with XSLT templates for the supported formats listed in the WMS's capabilities files. For example, if you open the directory of these templates at \Styles\WMS, you'll see the following:
- featureinfo_application_geojson.xsl
- etc
As their name implies, each template is used to produce a default GetFeatureInfo response in a readable format, such as GeoJSON, plain text, and XML.
You will not be able to retrieve feature geometry from an OGC Web Mapping Service (WMS) which is simply served as an image (raster).
In order to request a feature geometry (vector) from ArcGIS for Server I think you will need to use one of:
- ArcGIS for Server Feature Service
- ArcGIS for Server Geometry Service
- OGC Web Feature Service (WFS)

EPSG:4326 does not convert nicely into meters, but you can calculate the lengths of latitude and longitude degrees for example with http://www.csgnetwork.com/degreelenllavcalc.html
At 54°N the length of latitude is 111304.96 m and length of longitude is 65575.75 m.
Your BBOX is 0.1537 degrees high and 0.1977 degrees wide.
However, if you really want to have resolution in meters, use some projected coordinate system instead of EPSG:4326. For example UTM zone 35N should be good for Poland http://epsg.io/32635.
